Can You Grow Weed With A Medical Card?

Fact checked by Precious Ileh

Medical marijuana sells for anywhere between $5 and $20 per gram, depending on your location. This seems affordable at a glance, but that changes when it becomes a weekly expense. For instance, if you use marijuana for pain, you likely use about two grams daily. Since cannabis only manages the pain, you’ll have to use it every day. Even at the lowest price of $5 per gram, you’ll be spending at least $3,650 a year.

If this math has already crossed your mind, you’ve likely considered growing your own medical marijuana to save money. But can you do that without breaking the law if you have a medical marijuana card? The answer depends on where you live.

What’s a Medical Marijuana Card?

A medical marijuana (MMJ) card or medical cannabis card is a state-issued ID that allows holders to buy and use MMJ from licensed dispensaries legally. Some state governments and countries also recognize out-of-state cards and allow visiting holders to purchase or possess medical marijuana under certain conditions.

States typically issue medical marijuana cards only to patients diagnosed with qualifying conditions such as chronic pain, anxiety, epilepsy, or cancer-related symptoms. While each state has its own rules for issuing and using these cards, they all serve the same purpose — giving patients legal access to marijuana for therapeutic use.

Can I Grow Weed with a Medical Marijuana Card?

Some states allow medical cannabis cardholders to grow a limited number of plants at home for personal use. For example, in Arizona, you can grow up to 12 plants if you have an MMJ card and live more than 25 miles from a dispensary.

On the other hand, in Louisiana, you can get an MMJ card, but you can’t grow cannabis with it. In fact, MMJ patients caught cultivating cannabis in the state can face criminal charges, including fines and potential jail time.

In summary, not all states that issue medical marijuana cards allow patients to grow their own cannabis. MMJ patients can only cultivate plants in states that permit it, such as Arizona, Colorado, and California. Even in those states, they can grow only a limited number of plants, typically not more than 12.

States Where MMJ Cardholders Can’t Grow Weed

Several of the states that allow medical and recreational cannabis use don’t allow users to grow their own flower. Some of these states include:

Arkansas
Delaware
Florida (Shocking!)
Iowa
Louisiana
New Hampshire
New Jersey
North Dakota
Pennsylvania
Utah
West Virginia
Texas

If you’re an MMJ patient in one of these states, you have to get your dose from licensed dispensaries.

What Can You Do with a Medical Marijuana Card?

Besides being able to buy cannabis legally or grow it, depending on where you live, having an MMJ card comes with other perks. These perks typically vary between states. For example, in Vermont, MMJ cardholders may qualify to buy and possess more cannabis than recreational users. You also don’t pay tax on cannabis purchases, which is a big money-saver compared to paying 20 to 21% tax.

Other benefits across various states include access to a wider variety of cannabis products, including more potent ones. Lastly, depending on your local laws, a medical card can help you qualify for medical use exceptions in certain work or housing situations. For example, some states protect MMJ patients from job terminations for off-duty medical use or eviction from rental homes that don’t allow it.

Can I Use a MMJ Card Abroad?

An American MMJ card doesn’t give you the right to buy, possess, or use cannabis in a country where it’s illegal. However, if you’re visiting a country that recognizes medical use, it might allow you to carry approved prescriptions or documentation for certain cannabis-based medications.

For instance, your medical marijuana card won’t do you any good in strongly anti-cannabis countries like China and Singapore. But in France or the U.K., you may be able to travel with doctor-prescribed, cannabis-based medications if you follow their import rules.
