Q: How much medical marijuana can I have on me at one time?
A: You are permitted, by law in Canada, to have either 30 times the daily quantity of dried marijuana indicated by your prescription or medical document, or 150 grams of dried marijuana. Whichever is less. You cannot possess or store any amount of marijuana that exceeds this amount. You also need to show proof that you are legally permitted to possess and use marijuana for medical purposes in Canada.
