I got prescribed cannabis oil (but there is a catch)

I have chronic backpain for 20 years after a ski injury. Today, I went to Bangkok Integrative Medecine on Silom. My wife already booked an appointment yesterday.

On arrival, I filled a standard form about personal info, medical background, allergies, etc. The doctor received me and asked some more questions and examined my back. He prescribed me traditional Thai medecine herbs capsule and powder. The catch is that CBD and CBD+THC oil are sold out but they will send it by mail once they have it in stock again. Whole process took about 45 minutes and I paid 1400 baht.
