The greenRush Guide To
Medical Cannabis

An Introduction To Medical Cannabis

Cannabis has been used for medical purposes for thousands of years. Though federally restricted in the United States, 46 states have recognized the plant for its medical value. Individuals with cancer, chronic pain, nausea, epilepsy, and a host of other ailments have used medical cannabis throughout history for its healing properties. As more states legalize cannabis (medically and recreationally), researchers are looking to conduct more studies to demonstrate and support the effectiveness of the plant.

Medical Benefits Of Cannabis


Medical cannabis is often recommended for patients with serious physical or psychological conditions after other treatment methods have failed. For individuals with chronic pain, opioids (which can be addicting) are often prescribed first. Psychological ailments are often treated with therapy, sometimes in conjunction with medication. However, this doesn’t mean the medical use of cannabis is necessarily less beneficial.

Despite many individuals experiencing benefits from cannabis, research has been slow to verify these claims. There are a few exceptions where research has helped progress medical laws, for instance in the cases of cancer and epilepsy. However, with slow research comes slow legislation, directly influencing the distribution of medical marijuana to those in need. Since prescribing medical cannabis is federally illegal, doctors’ recommendations remain the only way to give patients access.

A few of the most common diseases and ailments treated with cannabis are mentioned below with additional details.


One of the most well-known benefits of cannabis is its ability to reduce seizures in many individuals with epilepsy. Reports of its benefits for individuals with seizures go back over 2,000 years. Of the 18 states that only allow low-THC, high-CBD cannabis, all specify that individuals with epilepsy or life-threatening seizures qualify to obtain the plant, with 14 of these allowing only these individuals access.

Studies investigating the effectiveness of cannabis for epileptic patients have found that THC is only a somewhat effective anti-convulsant, whereas CBD is more consistently beneficial. As CBD does not give individuals a head high like THC, research standards on this type of medical cannabis have been more relaxed. CBD application via oils and tinctures have been developed for epileptic patients under 18, with more researchers and parents arguing for studies on younger children and infants.


There unfortunately remains no cure for cancer, however cannabis can offer those with the disease some relief. Research on the benefits of cannabis for those with cancer started in the 1970s. Early studies in the 70s performed on rodents and some human subjects resulted in hopeful findings.

Many people who seek relief from cancer-related symptoms and chemotherapy, like pain and nausea, consider cannabis use alongside other medicines like opioids. A well-conducted study looking at cancer patients in advanced stages found that CBD helped lower pain associated with the disease with no long-term side effects. Surprisingly, THC did not significantly lower pain in these studies.

However, THC itself has “anti-tumor” effects. Several studies have found reductions in tumors associated with cancers of the skin, colon, breast, and others. While researchers are hesitant to use the word “cure”, people with early stages of cancer may experience some benefits from using THC combined with CBD to relieve pain and other negative symptoms.

Post Traumatic Stress Disorder (PTSD)

Epilepsy and cancer cause physical problems that can be monitored for improvement by researchers. PTSD, however, is a largely psychological disorder that causes individuals to experience severe nightmares, anxiety, and hyperarousal. Many states have been slow to include any psychological conditions, including PTSD in their list of applicable disorders and ailments that qualify for medical cannabis assistance.

Some exploratory studies have found significant improvements in symptoms, specifically with the use of THC. A number of other studies have focused on specific symptoms, rather than PTSD as a whole. For instance, cannabis has been found to reduce anxiety and insomnia, as well as stimulate positive mood.

Other Benefits

Numerous other medical benefits have been found via research studies and self-reports. Individuals with and without cancer have reported reductions in nausea after ingesting cannabis. Patients with chronic pain from multiple sclerosis and other diseases have reported extremely beneficial pain reduction after using cannabis as well.

Patients with a number of other ailments are legally able to receive assistance from medical cannabis under certain state laws, including those with HIV/AIDS, glaucoma, Parkinson’s disease, wasting syndrome, and Crohn's disease.

Treating With Medical Cannabis

An important consideration for medical users is whether they would benefit from a CBD or THC heavy product (or both). These naturally occurring compounds have similar benefits, but also differ in some respects. For example, CBD is helpful for reducing seizures and inflammation while THC can be used to help with insomnia and stimulate appetite. Both are known to reduce pain, nausea, and anxiety.

CBD has no psychotropic effects so users who do not like to feel the head high that comes with ingesting high-THC medical cannabis may want to opt for high-CBD products instead. CBD has very few side effects whereas THC can cause dry mouth and issues with coordination and memory. Plant growers should be aware that most sativa plant varieties contain higher levels of THC compared to indica plants.

Finding the exact cannabis strain that best suits a patient’s needs may take some trial and error. There are helpful guides online where medical and recreational users have noted the effects of different strains. Patients looking to reduce pain may benefit from strains like Blue Dream or Sour Diesel.

Although cannabis contains hundreds of compounds besides CBD and THC, the naturally-occurring concentration of each compound is too low to have any noted effects. However, researchers have begun studying certain compounds in higher concentrations with some promising findings. Early studies on cannabigerol (CBG) have demonstrated its ability to promote both bone and brain cell growth.

Medical cannabis is likely not a cure-all for every physical and psychological illness. For example, studies on anxiety and depression have shown mixed results. Numerous studies have found that excessive use of cannabis has been linked to higher levels of short-term anxiety and depression. However, social anxiety is a notable exception to this rule with users experiencing lower levels of anxiety during public speaking after using the plant.

Medical Cannabis Consumption Methods


There are a number of ways individuals can deliver cannabis into their system. The method of delivery can vary depending on personal preference, medical condition, or the law. For instance, most states that allow high-CBD, low-THC medical cannabis as a treatment only allow delivery as an oil to be rubbed on the patient's skin (topical application).

Here are the most common delivery methods for medical cannabis. It should be noted that the times listed are a rough estimate and depend greatly on the concentrations, doses, and the individual's body weight, metabolism, etc.

Smoking (Flower)

Smoking is the quickest way to experience the positive effects of medical cannabis, with effects felt within seconds of inhalation. After inhaling smoke through a joint, pipe, or bong, the effects often only last about 1-2 hours. While most people connect smoking with bad health habits, a few studies have found that smoking cannabis is less carcinogenic than smoking tobacco. Can't hold your breath for very long? One study found that people experience the same effects regardless of how long they hold the smoke in their lungs.



Vaping is another way to inhale marijuana and experience fast results. Smoking oil or flower through a vape heats up the cannabis to make it bind more effectively with receptors in the lungs. Inhaling cannabis without burning it also reduces the number of carcinogens entering the body. Individuals living in states with lax pesticide laws should consider vaping over smoking.


Edible medical cannabis can be infused into food or drink and is taken orally. The time it takes to impact the user takes about 45 minutes to an hour, and the effects can last for 3-4 hours. Individuals needing immediate relief may not like waiting this long, however, the longer effects can be beneficial for some. Consuming infused edibles may also be the preferred method for individuals who have lung issues.



Taking medical cannabis in the form of pills is another way to ingest the plant without inhaling smoke or smelling like cannabis. Like edibles, pills take about 45 minutes – 1 hour to have an effect and last for several hours. Pills can also contain synthetic cannabis, known as Dronabinol. These pills are high in THC and are prescribed by doctors to stimulate appetite in patients with AIDS, anorexia, or cancer patients undergoing chemotherapy.


Tinctures are made by using alcohol to extract the compounds from medical cannabis, giving users an alcohol-based cannabis liquid. Tinctures are highly concentrated so an eye dropper is often used with the product. A tincture can be added to any food or drink or dropped directly on or under the tongue. The effects will be felt after about an hour after mixing with food or drink or dropping on the surface of the tongue. The effects can be felt within minutes after dropping the tincture just under the tongue and holding it there for 30 seconds. Tinctures can be made at home and can limit the number of calories consumed compared to edibles.


Oils and topical creams created from plant infusion are a common delivery method for high-CBD low-THC cannabis. There are far more CBD than THC receptors on the skin, so rubbing THC-infused oil won’t have much of an effect. A number of states only allow oils for medical patients, particularly when delivering to persons under the age of 18. Oils and topicals are rubbed onto the skin and usually take at least a couple of hours to have an effect. Users of cannabis-infused topicals often use the product multiple times a day and begin to see positive effects within days or weeks.

Getting Cannabis In Your State

Getting Cannabis In Your State map legend

Access to cannabis differs greatly across the United States. While the scope of some states’ recreational use broadens, others still have zero tolerance policies, even for severe medical issues. For each state below, we describe the current medical cannabis laws in place, including qualifying conditions, personal allowances, and other important notes.

Note: "Typical conditions" refers to conditions often treated with cannabis such as HIV/AIDs, cancer, epilepsy/seizures, severe pain, and multiple sclerosis.


Very limited medical cannabis has been allowed in the heart of Dixie since 2014. In fact, less than 100 children and adults are currently receiving medical care with cannabis in the form of low-THC high-CBD oil. To qualify, patients must have severe epilepsy that has proven untreatable via other methods. The patient must be recommended by their doctor and can only receive treatment through a research study conducted by the University of Alabama-Birmingham. Pro-cannabis voters are looking to expand laws in the fall of 2018 after failing to do so in 2015.


The state of Alaska granted certain patients access to medical cannabis in 1998 and after numerous years of decriminalizing and re-criminalizing the plant, gave all residents access in 2014. Everyone over the age of 21 can have one ounce of usable cannabis plus 6 plants (no more than 3 mature) so having a medical cannabis card does not grant individuals any special treatment. The exception is if a doctor recommends cannabis as a treatment for individuals under 21; if so, a caregiver can have additional product and plants.


medical cannabis has been legal since 2011 and covers individuals affected by a number of diseases. These include the typical conditions mentioned above in addition to amyotrophic lateral sclerosis (ALS), hepatitis C, chronic nausea, Crohn's, glaucoma, Alzheimer’s, and wasting syndrome. While not every possible ailment qualifies, residents are allowed to request that certain diseases or symptoms be covered in order to expand the law. Patients can have 2.5 ounces of usable cannabis, purchased every two weeks. Qualifying individuals can also grow up to 12 plants if they live at least 25 miles from a dispensary.


Just under 6,000 medical cannabis cards have been granted since Arkansas allowed medical cannabis in 2016. In addition to the diseases covered by Arizona, Arkansas law also allows individuals with PTSD, Tourette's, ulcerative colitis, severe arthritis, fibromyalgia, or peripheral neuropathy to use cannabis. Patients not falling under one of these illnesses can petition the state and will hear back within 120 days. Growing plants is not allowed, however qualified patients can have 2.5 ounces of cannabis, purchased every two weeks.


California was the first state to legalize medical cannabis for qualified patient use in 1996. Recreational use was later brought into effect in 2018. Individuals with a debilitating medical condition, including the typical conditions listed previously, glaucoma, or other serious medical issues qualify for use/possession. Medical patients can have 8 ounces of usable cannabis, plus 6 mature plants or 12 immature plants. While medical limits and laws apply to patients throughout the state, recreational limits in the state are county dependent. Some medical patients may want to follow recreational laws while others stick to medical laws. One important bonus for medical patients is they don’t have to pay taxes on any cannabis purchases.


The state of Colorado approved medical cannabis in 2001 with 54% approval from voters. Patients with the following ailments (in addition to the typical conditions) can use cannabis as a treatment for: glaucoma, wasting syndrome, persistent muscle spasms, severe nausea, or PTSD. Recreational use was legalized in early 2014, allowing adults to possess one ounce of cannabis and up to 6 immature plants. Registered medical patients can grow the same amount but are allowed to purchase two ounces of cannabis from medical centers.


In 2012, Connecticut approved medical cannabis and has registered nearly 28,000 patients since then. Connecticut is one of only 15 states that explicitly lists Parkinson’s disease as a qualifying condition. Additionally, the law allows those with typical conditions or glaucoma, wasting syndrome, Crohn's disease, or PTSD access to cannabis. Patients can have 2.5 ounces of cannabis purchased only once a month.


Qualifying patients of Delaware rejoiced in 2011 when the state allowed cannabis to be used as a treatment method. In addition to the typical conditions, individuals with the following qualify for care: Alzheimer’s, severe nausea, autism with aggressive behavior, severe migraines, glaucoma, PTSD, ALS, or wasting syndrome. Patients are allowed to buy three ounces of usable cannabis every two weeks but cannot grow their own plants.


After 71% of Floridians voted to legalize medical cannabis in 2016, many residents were confused about the specific rules and regulations that came with the new law. Florida does not allow individuals to smoke the plant, in public or private. Also, the amount of cannabis a patient can have is determined by their doctor. Besides the typical conditions, the law allows individuals with glaucoma, PTSD, ALS, Crohn's disease, or Parkinson's to access cannabis.


Only medical cannabis in the form of low-THC high-CBD oil is allowed in Georgia as of 2015. Medical patients can possess up to 20 ounces of weed oil; any more is a felony. To qualify, patients must have a common condition or ALS, severe autism, Crohn's, Parkinson’s, PTSD, or Tourette’s. Patients in hospice programs also qualify.


Hawaii has allowed access to medical cannabis since 2000 for individuals with the typical conditions listed or glaucoma, lupus, arthritis, severe nausea, PTSD, or Crohn's. The state is more liberal in their allowances compared to most states, letting patients have four ounces and 10 mature plants. Patients without a green thumb were relieved when dispensaries opened in 2015.


As long as Governor C.L. "Butch" Otter is in office, cannabis will remain illegal at the recreational and medical level in Idaho. In 2015, the governor struck down a bill that would have allowed parents of children with severe epilepsy to use CBD oil as a treatment method. As only one of four remaining states to disallow even this most basic level of care, Idaho citizens may need to look elsewhere for symptom relief.


The state passed a law in 2013 allowing patients to receive 2.5 ounces of cannabis within a two-week period. Illinois lists 40 specific diseases or symptoms covered under the medical law. In late August of 2018, the state passed an additional bill that allows for an easier application process in the hopes patients will opt for cannabis-based treatments over opioids.


Indiana only recently granted patients access to medical cannabis in early 2018. Low-THC, high-CBD oil is permitted for patients with severe epilepsy for whom two alternative treatments have failed. The law does not specify purchasing limits.


Patients with severe epilepsy are eligible to receive low-THC, high-CBD oil in Iowa as of 2014. The law states that the neurologist who recommends the medical cannabis oil needs to have tried other treatment methods without success. Patients can have up to 32 ounces of oil which needs to be "free from plant material."


Despite how fun it is to say, cannabis in Kansas is still illegal though somewhat decriminalized. In mid-2018, Governor Jeff Colyer distinguished CBD as being different from marijuana. However, since even products with trace amounts of THC are illegal, CBD oil is not likely to hit the market anytime soon.


Like Kansas, Kentucky’s definition of cannabis does not include CBD. Low-THC, high-CBD oil is available but only to a select number of patients with epilepsy who are involved in a research study at specific universities. While the Governor is supportive of medical cannabis, previous bills (including one in early 2018) haven’t made headway in the House or Senate.


Qualified medical patients in the Bayou state will be able to start receiving cannabis in late 2018. To qualify, patients must have one of the typical conditions listed above or wasting syndrome, Crohn's, or muscular dystrophy. A patient's doctor will determine how much the patient is eligible to receive from a dispensary during a one-month period.


Maine was one of the earliest advocates of medical cannabis, allowing patient care since 1999. A patient qualifies for care if they have one or more of the typical conditions listed or hepatitis C, Crohn's, glaucoma, or Alzheimer’s. Patients can have 2.5 ounces of cannabis and six mature plants. Despite the current anti-cannabis Governor, Maine has legalized recreational marijuana which will be available from dispensaries in early 2019. Recreational users will likely be allowed less cannabis than medical users so patients should make sure they stay registered.


Maryland allowed patient access to cannabis in 2014 although dispensaries did not open until late 2017. To qualify for cannabis care, patients must have a typical condition or PTSD, anorexia, wasting syndrome, severe nausea, or glaucoma. There are no clear rules on quantities allowed, but a patient’s doctor is likely in charge of determining their patient’s one-month supply limit. Patients are not allowed to grow their own plants.


Over 50,000 patients have received medical cannabis through the state of Massachusetts since it became medically legal in 2012. These patients have one or more of the following conditions in addition to the typical conditions listed previously: glaucoma, hepatitis C, ALS, Crohn’s, or Parkinson’s disease. Medical users can purchase up to 10 ounces per 60 days, whereas recreational users can only purchase one ounce at a time. While legalized recreationally in 2016, dispensaries are not expected to open until late 2018.


Michigan approved cannabis for medical use in 2008, allowing qualified patients to possess up to 2.5 ounces and 12 plants. Michigan recently added 11 new conditions to the existing list, including autism and arthritis. Most notably, obsessive-compulsive disorder (OCD) was added, however other psychological disorders, including debilitating depression and anxiety, were rejected from qualifying for medical cannabis.


Like Florida, Minnesota does not allow patients to smoke cannabis flower. Pills and oils are allowed and oils can still be smoked through a vaporizer. In addition to the typical conditions, individuals with ALS, glaucoma, Tourette's syndrome, Crohn's, ALS, or any terminal illness can access medical marijuana. Patients can have a 30-day supply which is determined by the patient’s doctor.


Mississippi is another state that only allows access to medical cannabis in the form of low-THC, high-CBD oil. Patients must suffer from epilepsy or severe seizures and be enrolled in a research study at a qualifying university. Cannabis plants can be grown by the university and converted into usable oil for patients.


Residents of Missouri are aware of the lax laws surrounding alcohol consumption in the state. In most areas, passengers can drink in vehicles, adults can drink in public, and liquor is sold until 1:30 am. So, it's surprising that Missouri has tight restrictions on cannabis, only allowing patients with epilepsy to receive treatment via low-THC high-CBD oil. These patients can’t receive care until three or more other treatment methods have failed and they can only pick up the oil from one of two available centers.


As of 2004, Montana allows patients to have one ounce of usable cannabis, 4 mature plants, and 12 immature plants. Qualifying patients must have one of the typical conditions and/or glaucoma, wasting syndrome, severe nausea, Crohn's, PTSD, or be in hospice care. The state began taxing cannabis in mid-July and brought in $1.8 million in just a year.


Nestled in between two other anti-cannabis states (Kansas and South Dakota), Nebraska doesn’t see a lot of cannabis. Governor Pete Ricketts is firmly against legalizing the plant at the state level, issuing a statement that makes it clear he will wait for federal approval before allowing citizens access to recreational or medical cannabis.


Nevada gave patients access to cannabis in 2000 and all adults over 21 access in 2017. Medical patients qualify to receive cannabis if they have one or more of the typical conditions, glaucoma, or severe nausea. Recreational users can have one ounce of marijuana and 6 mature plants if they live more than 25 miles from a dispensary. Medical patients are allowed 2.5 ounces and 12 mature plants, regardless of where they live.

New Hampshire

Medical patients in New Hampshire have had access to cannabis since 2013 with expansions passed in 2017. A number of patients qualify including those with the typical conditions, PTSD, traumatic spinal cord or brain injury, Parkinson’s, lupus, and numerous others. Patients can purchase 2 ounces during a 10-day period at a registered dispensary.

New Jersey

New Jersey granted patients access to cannabis in 2010, however, the law has some odd components. For example, only patients under 18 can purchase edibles. Numerous conditions qualify a patient for cannabis access, including anxiety, migraines, Tourette’s, the typical conditions, and others. Patients can possess up to two ounces of cannabis.

New Mexico

As of 2007, residents of New Mexico qualify for medical cannabis if they have one of the typical conditions, glaucoma, PTSD, Parkinson’s, or a number of other conditions. Interestingly, nearly half of all registered patients have PTSD and a third suffer from chronic pain. Patients can have up to 6 ounces of cannabis, 4 mature plants, and 12 immature plants.

New York

Patients were granted access to cannabis in 2014, however it is illegal to smoke the plant or consume infused edibles. Patients qualify if they have a typical condition, ALS, Parkinson’s, spinal cord injury, Huntington’s disease, or PTSD. The amount a patient can receive in a 30-day period is determined by their doctor.

North Carolina

North Carolina joins the low-THC, high-CBD oil only states, allowing patients with epilepsy to enroll in university studies to gain access. This program was first launched as a pilot in 2014, with a full study allowed in 2015.

North Dakota

Just over 63% of North Dakota voters agreed to provide patients access to medical cannabis in 2016. Qualifying patients must have a typical condition, ALS, hepatitis C, Alzheimer’s, Crohn's, glaucoma, or wasting syndrome. The state allows patients to have three ounces or 8 plants if living more than 40 miles from a dispensary.


A house bill was passed in 2016, granting cannabis access to patients in need. Ohio considers a number of qualifying conditions including Alzheimer's, Crohn's, sickle cell anemia, Tourette's, and numerous others. A patient's doctor will determine how much a patient needs within a 90-day period, which can be purchased at a dispensary but not personally grown.


Despite the slow approval of medical cannabis in August 2018, patients are able to possess more cannabis than medical patients in most other states. The law allows patients to have three ounces of cannabis on them, eight ounces at home, six immature plants, six mature plants, and 72 ounces of edible cannabis. Surprisingly, the law does not define which conditions qualify a patient to receive cannabis. It will be up to a doctor to make these decisions.


Medical patients have had access to cannabis since 1998, however, it wasn't legalized recreationally until 2015. Patients with one of the typical conditions, glaucoma, severe nausea, or PTSD qualify for medical use. Medical patients are allowed 24 ounces of cannabis and six mature plants. Recreational users can have one ounce in public, eight ounces at home, and four mature plants. Unsurprisingly, many medical patients aren't bothering to apply for medical access as recreational laws give plenty of access to cannabis.


A Senate bill passed with flying colors in 2016, allowing patients access to cannabis. A large number of conditions are covered under Pennsylvania’s medical cannabis laws, including the typical conditions, autism, PTSD, Parkinson’s, sickle cell anemia, Crohn's, and many others. Patients can have a 30-day supply, dictated by their doctor.

Rhode Island

Patients with the typical conditions, severe nausea, wasting syndrome, glaucoma, or hepatitis C have been eligible to receive cannabis since 2006. Patients can have up to 12 mature plants and 2.5 ounces of cannabis. Despite annual recreational proposals being submitted for the past 7 years, all have been dismissed.

South Carolina

South Carolina follows similar rules to their neighbor to the north. Only patients with severe epilepsy can utilize low-THC, high-CBD oil as a treatment. Although oil must be accessed through a university study, some individuals have allegedly found loopholes and have legally produced their own.

South Dakota

Residents of South Dakota will not be able to access medical cannabis anytime soon. Not only have previous bills been struck down, prior attempts to add propositions to the ballot have not been successful. Additionally, the state hasn’t decriminalized the plant so penalties for possession are comparatively harsh.


Patients with severe epilepsy are allowed to enter a university research study to access low-THC, high-CBD oil as a treatment option. The university researchers are not allowed to obtain the oil from inside the state. The study began in 2014 and should be concluding in late 2018.


As of 2015, Texas has allowed limited access to medical cannabis for individuals with epilepsy through a compassionate care program. To enroll, two physicians have to recommend low-THC, high-CBD oil after other methods have failed, but, unlike many states, the patients do not need to be enrolled in a university study to receive care.


In 2014, the state of Utah allowed individuals with severe epilepsy to receive treatment via university studies, but only in the form of low-THC, high-CBD oil. The law is confusing but allows university researchers to make their own oil with hemp extracts.


As of 2004, patients with the typical conditions are eligible to receive medical cannabis as well as those with severe nausea and wasting syndrome. Recreational cannabis became legal in 2018, allowing persons to have one ounce of cannabis, two mature plants, and four immature plants. However, cannabis can only be purchased from dispensaries by medical users. Registered medical users can have two ounces of cannabis, two mature plants, and seven immature plants.


As of 2015, patients with severe epilepsy are eligible to obtain low-THC, high-CBD oil and do not have to be enrolled in university research. Patients should be wary; Some authorities recommend purchasing the oil from outside the state via online methods because in-state oil is of a lower quality.


In 1998, voters allowed medical patients to access medical cannabis and, in 2012, Washington was the first state to legalize cannabis for recreational use. Patients must have one of the typical conditions, Crohn's, hepatitis C, traumatic brain injury, anorexia, or PTSD to become a medical patient. Medical users can purchase up to three ounces of cannabis, 48 ounces of edibles, and 216 ounces of cannabis in liquid form (e.g., oil), all tax-free. Recreational users can purchase up to one ounce of cannabis, 16 ounces of edibles, and 72 ounces in liquid form.

Washington D.C.

Washington D.C. allowed patients to access medical cannabis in 1998, and, despite its illegality at the federal level, legalized recreational use in 2014. Patients with any medical condition that a doctor thinks would benefit from medical cannabis can qualify for medical use. Medical users can have up to four ounces and six plants. Recreational users can have up to two ounces of cannabis and six plants, three of which can be mature.

West Virginia

Unlike most other states, West Virginia does not specify who is qualified to receive medical cannabis, leaving it up to physicians to decide. Limits are also not specified; however, the law passed in 2017 does note that cannabis flower is not allowed. Patients can only access cannabis through one of 30 dispensaries allowed in the state, and only in non-flower forms like edibles and oils.


In 2005, Wisconsin allowed individuals with severe seizures to use low-THC, high-CBD oil as a treatment method. Patients need to acquire the oil from outside of the state as the law does not permit anyone to manufacture cannabis within the state. Unfortunately, the THC and CBD limits are not defined, so it's not clear what makes an oil illegal for use.


In 2015, the state of Wyoming granted patients with severe epilepsy the ability to use low-THC, high-CBD oil. Manufacturing the oil is not allowed in the state, so patients have to purchase the oil from beyond state lines.
