Medical Marijuana in the USA: A Visitor's Guide for British Travellers

By ZenNews Editorial May 28, 2026 1 min read

Medical cannabis is legal in over 38 US states — but access for foreign visitors is considerably more complicated than simply walking into a recreational dispensary. Understanding the realistic options and the hard limits of the system is essential for anyone navigating US cannabis medicine as a traveller.

How the US Medical Marijuana System Works

Consultation with a state-licensed cannabis physician (in-person or via telemedicine)
Qualifying diagnosis — conditions accepted vary by state
Physician's written recommendation
Application for a Medical Marijuana Card with the state health authority
Purchase from licensed medical dispensaries

Commonly accepted conditions: chronic pain, cancer, multiple sclerosis, epilepsy, PTSD, glaucoma, HIV/AIDS, Parkinson's disease and Crohn's disease.

Which States Allow Foreign Nationals Access?

State	Visitor Access	Practical Reality
California	Possible (recreational also legal)	Recreational purchase simpler; medical useful for specialist products
Colorado	Recreational also legal	Medical card offers higher limits and lower prices
Oregon	Recreational sufficient	Cheapest prices; medical pathway not worth pursuing for short stays
Nevada	Recreational also legal	Medical card not necessary for most visitor needs
Florida	In principle residents only	Telemedicine evaluation possible but card processing takes weeks
Texas	Effectively inaccessible for visitors	Very narrow programme, not practical for short visits

Medical vs Recreational: Key Differences

Product access: Medical dispensaries carry stronger products and specialist formulations
Possession limits: Medical patients typically hold larger quantities
Tax: Medical purchases are tax-exempt or low-taxed — up to 25% cheaper
Age: Medical cards can be issued to under-21s with a physician's recommendation

Costs

Physician consultation: $50-200
State medical card fee: $25-200 depending on state
Processing time: often one to four weeks — not practical for short visits
Telemedicine consultations: typically $60-150

Longer Stays

British nationals living in the US for extended periods can apply for medical cards in the normal way if resident in a medical state. Requirements typically include proof of residency, valid passport, qualifying diagnosis and the state application fee.

The Absolute Rule: Nothing Comes Home

Transporting cannabis or cannabis products from the US to the UK is a serious international criminal offence. Border Force at UK airports specifically trains for these products. Consequences range from confiscation to prosecution.
