Consuming cannabis in Alberta is allowed where tobacco smoking is currently allowed see Tobacco and Smoking Reduction Act (Section 3) with some additional provincial restrictions included.
Cannabis smoking and vaporizing lounges or clubs will not be allowed unfortunately!
These types of businesses would be very helpful in providing education on healthy responsible ways to consume and could also provide harm reduction benefits.
