First, you must be enrolled in Oregon’s Medical Marijuana Programme — available only to residents of the state. Joining requires a $100 (£60) fee and a doctor’s certificate confirming that you suffer from cancer, glaucoma, Aids, Alzheimer’s, or any condition that results in severe pain, appetite loss, spasms, seizures, or nausea.

Only after being issued with a patient ID card are you allowed to join the Oregon chapter of the National Organisation for the Reform of Marijuana Laws (NORML), which costs $240 a year. Patrons must show their patient ID and NORML membership cards before being let through the doors of the Cannabis Café.

As for the price of a hit — it’s free.
