According to Health Canada, you are only allowed to place an order for and buy 30 days worth of marijuana at a given time. For example if your prescription is 1 gram per day, for 3 months, the most that you can buy at a time is 30 grams of marijuana. You must contact your Health Canada approved medical cannabis provider 30 days after you have purchased your first month’s supply to purchase the next month’s supply of medication. Please remember that you are only allowed to purchase more medication within a 30 day period if you are written a prescription for a greater dose during those 30 days. You are legally allowed to carry with you the maximum amount of marijuana that you are permitted to buy for 30 days (in the example above this would be 30 grams). There are many intricacies to purchasing Medical Marijuana, many of which are regulated by Health Canada. O Cannabis Clinic and/or your Licensed Producer will help you manage these intricacies. Should you have any questions about this process, please contact your licensed producer or O Cannabis Clinic directly.
