Is marijuana/cannabis legal in California? What about the rest of the United States?

Yes, cannabis is legal in California, as long as the person is not carrying too much and is aged 21 or over (18 or over for medical marijuana patients). However, cannabis is still federally illegal, and you cannot carry it over state lines, even between two legal states. Alaska, Colorado, Maine, Massachusetts, Nevada, Oregon, Vermont, Washington and the state district of Washington,. D.C. also have legal recreational and medical marijuana. Arizona, Florida, Hawaii, Michigan, New Mexico, North Dakota, Arkansas, Connecticut, Delaware, Illinois, Maryland, Minnesota, Montana, New Hampshire, New Jersey, New York, Ohio, Rhode Island, West Virginia and the U.S. territories of Guam and Puerto Rico have medical marijuana laws in place. Some of these states have also decriminalized non-medical possession to some extent, but that still means fines and felony charges.

How much cannabis can I carry?

Technically, a medical marijuana patient can possess on themselves “as much as is deemed necessary”, but we don’t recommend testing this theory out when it comes to extreme amounts! Those without a medical marijuana card may carry up to a maximum of 1 ounce (28.5 grams) of dried cannabis flower/bud, or 8 grams of cannabis in concentrated form (waxes, butters, hash, edibles, tinctures etc.). If you are carrying 14.25 grams of cannabis flower, you may only possess a maximum of 4 grams of concentrate.

Just ensure you have a working microphone, camera and internet connection, and you can get talking to one of the doctors at Leafwell within a few minutes after signing up. We can only provide recommendations and medical marijuana cards for those who are from California.

How old do I have to be in order to apply for a medical marijuana card?

You must be aged 18 or over in order to apply for a medical marijuana card in California, whether for yourself or as a caregiver.

What do I need to have for my medical marijuana evaluation?
  • Photographic ID (e.g. driver’s permit/license or a passport)
  • Proof of address (e.g. utility bill, mortgage/rental agreement, bank statement)
  • Helpful but not always necessary – medical records (e.g. patient history, doctor’s notes, imaging/scan results; list of other medications being taken can also be helpful)


What conditions qualify me for medical marijuana?

In California, suffering from one or more of the following may qualify you for medical marijuana/cannabis:


Can physicians at Leafwell recommend patients in other states?

No. California state laws only allow physicians licensed by California to practice medicine. All other US states follow similar rules, as far as we know.

How much does it cost to get a medical marijuana recommendation and card?

$49 for just the physician’s recommendation letter. $59 for both the recommendation letter and medical marijuana card (subject to change).

What happens if I qualify for a recommendation and medical marijuana card?

You will be sent a recommendation letter via email, containing your unique ID number, your date of birth and the physician’s signature. This can be used to gain access to dispensaries that see only medical patients, and will identify you as a medical patient in dispensaries that accept both recreational and medical cannabis users. If requested, we will send you a hard copy of the letter and your medical marijuana card to the address you’ve provided, as long as that address is based in California. The medical marijuana card will contain your patient number, your name, date of birth, and date of issue and expiry. Your patient number can be verified at Your name will not be visible on this website if the number is put through – it will only tell whoever’s checking the card that the recommendation is valid and in-date.

Do recreational laws affect medical cannabis patients in any way?

Technically, no. Prop. 215 remains the same, and medical marijuana patients are still covered by it and SB 420 to some extent. However, due to the new recreational laws, the parts of SB 420 that effectively allowed cannabis growers to work as a co-operative are repealed to some extent, so it is arguable that recreational laws have had an effect on medical cannabis users and caregivers to a certain extent. There are possibly some indirect effects as well.

Unfortunately, answering all of your health-related medical marijuana questions on one page would be an almost impossible task. That’s why we have a “Conditions” page where we go through cannabis’s use for many different conditions.

Does having a medical marijuana card save me money on cannabis flower and products in California?

Having a medical marijuana card and recommendation will exempt you from sales taxes. Other state and excise taxes are still applicable. However, as sales taxes can account for around 10%-20% of the total cost of cannabis, having a valid rec and MMJ card would mean significant savings.
