With more than half the U.S. operating some form of marijuana program or another, differences between state medical and recreational marijuana programs abound. Have you ever asked yourself, “How much weed can I buy?” Check out this state-by-state guide!

Alaska

Alaska has passed both medical and recreational marijuana laws, in 1998 and 2014 respectively. Under these two legal mechanisms, dispensaries may sell limited amounts of cannabis to both patients and consumers. Medical marijuana patients, their registered caregiver, and recreational weed consumers all share the same purchase limit: a quantity of one ounce (28 grams) per transaction.

Arizona

Arizona passed their medical marijuana program in late 2010, allowing patients with certain health conditions across the state access to alternative medicine where federally approved medicines or treatments have failed. Patients are eligible to purchase as much as 2.5 ounces (70 grams) every 14 days. Whether purchased in full during one transaction or in several smaller purchases, this effectively caps monthly purchasing at five ounces.

Despite several attempts, Arizona voters have yet to legalize recreational marijuana.

Arkansas

Voters in Arkansas passed medical marijuana laws in 2016. While the state has yet to fully implement the industry, regulations have set purchasing limits for patients at 2.5 ounces of marijuana flower every two weeks, setting, like Arizona, a monthly total of five ounces.

California

California kicked off the medical marijuana industry as the first state to pass such legislation in 1996. Voters across the state again threw support towards cannabis law reforms in 2016, legalizing the plant for all adults 21 and older. Though lawmakers in the state are expected to implement further regulations on product testing, licensing, or public safety concerns (which may possibly include stricter controls on patients’ marijuana supply), medical marijuana patients can buy up to eight ounces of fresh marijuana per day. EIGHT OUNCES!!!

Recreational customers are, conversely, limited to purchasing as much as one ounce per day.

Colorado

Colorado has both medical and recreational laws within the state constitution, voted on in 2000 and 2012 respectively. Medical marijuana patients may purchase as much as two ounces per day, while recreational consumers have weed purchase limits defined by product category.

Recreational consumers in Colorado can buy weed in the following amounts:

  • Up to one ounce of flower
  • Up to eight grams of concentrate
  • Up to 800 mg of edible marijuana products

Connecticut

As of 2017, Connecticut has only a medical marijuana program in place. Patients are allowed no more than 2.5 ounces (70 grams) in any 30-day period. Patients can receive less than this total at the doctor’s request, but never more.

Delaware

Delaware began their journey with medical marijuana in 2011. Patients in the Delaware medical marijuana program can buy weed up to six ounces per month. This total, however, can only be reached at a rate of three ounces every two weeks.

Florida

Florida has taken a very narrow approach to allowing the medical use of marijuana within state borders, starting first with a CBD program for a specific type of seizure disorder and full-strength, THC-filled cannabis for ONLY the terminally ill in 2014. In 2016, voters in the state chose to expand the program to include more conditions, among other changes. Amendment 2, the bill expanding the medical marijuana program, permits:

“the amount of marijuana that could reasonably be presumed to be an adequate supply for qualifying patient’s medical use, based on the best available evidence. This presumption as to quantity may be overcome with evidence of a particular qualifying patient’s appropriate medical use.”

This has been determined to mean a 45-day supply, at most. The physician is the individual who determines patient dose, so this amount depends on the individual and their condition.

Hawaii

Hawaii joined the full Pacific Coast of the U.S. in legalizing medical marijuana by 2000. Under the law, patients can buy as much as four ounces of weed every 15 days.

Illinois

The Illinois State Legislature, rather than state residents, voted on (and passed) medical marijuana laws in 2013. Under the “Compassionate Use of Medical Cannabis” program, patients are able to buy weed up to 2.5 ounces every two weeks, roughly a total of five ounces a month.

Maine

Residents of Maine have voted for both medical and recreational cannabis laws, passing in 1999 and 2016 respectively. Patients operating under Maine’s medical marijuana program as well as prospective recreational marijuana consumers can buy marijuana up to 2.5 ounces. Medical patients are limited to five ounces per month unless their physician authorizes more.

Maryland

Maryland passed medical marijuana laws in 2011, yet the program has not produced a dispensary to this day. While the program has been hindered by legislative delays, legal battles, regulatory confrontations, and a mixed bag of administrative cajoling, once implemented, patients will be able to buy weed up to 120 grams (just under 4.25 ounces) in a single purchase.

Massachusetts

Massachusetts has both medical and recreational cannabis laws; however, only one of the two programs has been fully implemented. Recreational sales are expected in 2018. Under the medical marijuana program, patients can buy weed up to 10 ounces every two months. In contrast, recreational consumers will be able to buy weed up to one ounce OR as much as five grams of marijuana concentrates.

Michigan

Michigan now has one of the largest medical marijuana communities in the U.S., following the 2008 passage of the “Michigan Medical Marijuana Act.” Patients in Michigan can buy weed up to 2.5 ounces. The state has further drawn equivalencies based on product form. They are as follows.

In Michigan, One ounce of marijuana flower is equal to:

  • 16 ounces of cannabis-infused products in solid form (such as cannabutter)
  • 7 grams of extracted cannabis product in a gaseous form (presumably a form used in a vaporizer)
  • 36 fluid ounces of cannabis-infused product in a liquid form (such as an oil)

Minnesota

Minnesota began their journey with medical cannabis in May 2014. Under the Minnesota Medical Marijuana Program, patients are required to have a consultation with a pharmacist after receiving approval to join the medical program from a physician. During the consult, the pharmacist will determine an adequate volume of cannabis products to treat the patient for 30 days on an individual basis.

In other words: Minnesota has no predetermined purchase limits.

Montana

Montana has oscillated back and forth on the issue of medical marijuana, allowing the industry to grow, then shrink, be lobbied to change, and achieve voter support. The passage of laws supporting the growth of the statewide medical marijuana in 2016 will, once fully implemented, allow medical patients access to one ounce of marijuana per purchase.

Nevada

Nevada passed their medical marijuana program in 1998. In 2016, recreational cannabis laws followed. Today, the state boasts a robust cannabis industry. Under the laws, medical marijuana patients can buy as much as five ounces per month, so long as purchases are limited to 2.5 ounces every twoweek period.

Recreational consumers are limited to buying weed up to one ounce. Nevada has further defined product equivalencies for recreational weed consumers, limiting concentrate purchasing to 3.5 grams.

New Hampshire

New Hampshire currently has only a medical marijuana program. Under state laws, medical marijuana patients possessing a valid state registration can buy weed up to two ounces of marijuana flower in any 10-day period, providing a total of six ounces per month if needed.

New Jersey

New Jersey legalized the medical use of marijuana in 2010, though the program remains one of the most heavily scrutinized by state agencies. Patients registered with the medical marijuana program are first evaluated by their physician, who will then send an order to the dispensing location for the total dosage a patient may purchase in a 30-day period. The physician order cannot exceed two ounces per month.

New Mexico

New Mexico has had medical marijuana laws on the books for a decade, spurring a robust patient and grower community across the state. Patients can, under state law, buy weed up to 230 units of marijuana in any 90-day period.

So what are “units” of marijuana?

In New Mexico, a unit is equal to one gram of marijuana flower or 0.2 grams of marijuana concentrates. Under this guideline, patients can buy just over 2.7 ounces of flower or 15 grams of marijuana concentrate per month.

New York

New York passed the “Compassionate Care Act” in 2014, providing a legal pathway to an alternative treatment to those who need it. The program requires the authorizing medical professional (physician or nurse practitioner) to determine a 30-day supply for each patient on an individual basis. How much weed you can buy, therefore, is dependent on the condition and symptoms you experience.

North Dakota

Voters backed the initiative to legalize medical marijuana usage in 2016. At the time of writing, the program is yet to be fully operational. When it is, patients will be able to buy weed up to 2.5 ounces in any 30-day period.

Ohio

Lawmakers in Ohio passed medical marijuana legislation in September 2016. The state has one of the most regimented controls on medical cannabis purchasing in the U.S. Under the state medical marijuana program, every 90 days a non-terminal (not dying) patient can buy weed in the following amounts:

  • Up to 8 ounces of tier I medical cannabis
  • Up to 5.3 ounces of tier II medical cannabis
  • Up to 26.55 grams of THC content (totaling 26,550 mg of THC) in patches, lotions, creams, and other topical forms
  • Up to 9.9 grams (9,900 mg) of THC from cannabis oil, tincture, capsules, and other edible forms
  • Up to 53.1 grams (53,100 mg) of THC in oil for vaporization

Patients with terminal diseases or illness, under Ohio’s medical marijuana program, are given the following limits on their purchasing over 90 days:

  • Up to 10 ounces of tier I medical cannabis
  • Up to 6.6 ounces of tier II medical cannabis
  • Up to 33.3 grams (33,300 mg) of THC in patches, lotions, creams, etc.
  • Up to 11.7 grams (11,700 mg) of THC in oils, tinctures, capsules, and edibles
  • Up to 65.7 grams (65,700 mg) of THC in cannabis oils for vaporization

Tier I marijuana is defined as medical cannabis testing at or below 23% THC while tier II medical cannabis tests above 23% but not more than 35%.

Oregon

Oregon first passed medical marijuana laws in 1998, followed by recreational marijuana laws in 2014. Patients registered with the Oregon medical marijuana program can buy weed up to the following limits:

  • Up to 24 ounces of marijuana flower
  • Up to 16 ounces of a medicinal cannabinoid products in solid form (such as cannabutter)
  • Up to 72 ounces of a medicinal cannabinoid product in liquid form (such as tincture)
  • Up to 16 ounces of a cannabinoid concentrate (such as oil)
  • As much as five grams of a cannabinoid extract (such as live resin)

Recreational consumers are legally bound to different limits than medical patients. Take a look:

  • Up to one ounce (28 grams) of usable marijuana flower
  • Up to six ounces of a cannabinoid product in solid form
  • Up to 72 ounces of a cannabinoid product in liquid form
  • As much as five grams of cannabinoid extracts or concentrates

Pennsylvania

Pennsylvania has legalized the medical use of marijuana; however, the program has not yet been fully implemented. Under the program rules, the recommending physician is to determine the volume of medical marijuana necessary to supply a patient for 30 days, therefore allowing each patient to receive an individualized health plan. So the amount of weed you can buy in Pennsylvania truly depends on your condition.

Rhode Island

Rhode Island passed laws in 2006 making the medical use of marijuana legal under certain conditions. At the time of writing, the program is fully operational, allowing patients to buy weed up to 2.5 ounces of marijuana in any 30-day period.

Vermont

Vermont wants to legalize marijuana, yet attempts made thus far have yet to get them there. Instead, the state has over a decade of medical marijuana laws, which began in 2004. Patients registered with the Vermont medical marijuana program can purchase as much as two ounces in any 30-day period.

Washington

In 1998 and 2012 respectively, Washington passed medical and recreational cannabis laws. Today, much of the medical marijuana program has been streamlined into the regulatory framework built to govern the recreational industry. However, differences between the two program still exist. If you are wondering how much weed you can buy in Washington, medical patients registered with the state are limited to the following:

  • Up to three ounces of marijuana flower
  • Up to 48 ounces of marijuana-infused products in solid form
  • Up to 216 ounces of infused marijuana product in liquid form
  • Up to 21 grams of marijuana concentrates

Recreational marijuana consumers, however, are limited to buying weed in the following quantities:

  • up to one ounce of marijuana flower
  • up to seven grams of marijuana concentrate
  • up to 16 ounces of marijuana-infused product in solid form
  • up to 72 ounces of marijuana-infused product in liquid form

Washington, D.C.

Washington, D.C. has both medical marijuana and recreational marijuana laws. The medical marijuana program began in 2010, though it was originally proposed in 1998. The recreational marijuana laws create a legal framework where adults 21 and over can possess, grow, and use marijuana legally, but did not include a mechanism to sell cannabis legally.

Medical marijuana patients in Washington D.C. can buy weed up to two ounces in a 30-day period.
