How 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, 
  • 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.
