Manitoba retailers who sell cannabis have to follow strict rules about how they display and secure the drug.

New rules set by the province will mean stores have to use monitored alarm systems and video cameras that operate continuously.

Cannabis needs to be locked cases, except for small display containers that can be inspected by customers but still secured with a chain or other ways.

Other rules the province announced is a 30-gram limit on individual sales and requirements to verify the age of customers to ensure they are 19 or older.
