Rules
← BackHow much cannabis can you have in public?
An adult (18+) in Alberta is legally allowed to possess up to 30 grams of legally produced dried-cannabis (or the equivalent volume in other forms) in public.
The Government of Canada has developed ratios for other cannabis products that can be used to determine a possession limit for those products.
One (1) gram of dried cannabis is equivalent to:
- 5 g of fresh cannabis
- 15 g of edible product
- 70 g of liquid product
- 0.25 g of concentrates (solid or liquid)
- 1 cannabis plant seed
Growing cannabis at home
- Albertans wishing to cultivate a small personal supply of cannabis can purchase their seeds from a provincially regulated retailer or through Alberta’s only legal online retailer, albertacannabis.org
- Albertans are permitted to grow up to four cannabis plants per residence for personal use from licensed seeds.
- Renters, condo-dwellers and those who live in multi-family dwellings might be restricted from growing cannabis in their homes based on rules established in rental agreements or condominium bylaws.
- Individuals may not designate another person to grow recreational cannabis on their behalf.
- Cannabis for medical purposes is the only exception to the above rules. For more information on medical cannabis, please visit Health Canada.
How can I home grow safely?
- Cannabis products can harm children and pets. Lock your grow space and products and dispose of waste safely.
- When home growing or storing cannabis, keep the Alberta Poison and Drug Information Service number handy and close by: 1-800-332-1414. If you think your child has ingested cannabis call this number.
- Keep your indoor air healthy. Monitor humidity levels. Use dehumidifiers and a carbon monoxide detector as needed both inside and outside the growing area.
- Limit, select and carefully use pesticides. Even food-grade pesticides were not safety-tested for typical cannabis use.
- Be aware of your building's electrical and fire safety limits.
- Grow safely and within the law. Organic solvents for cannabis processing are dangerous and have legal consequences.
- Check with your landlord or building manager for any restrictions before starting up a home grow space.
- Limit ultraviolet light exposure to your eyes and skin.
