Marijuana rules and regulations are tough to keep up with. Denver lawmakers have tentatively approved a proposed ordinance to impose caps on the number of marijuana retail and cultivation sites in the proverbial capital of the cannabis industry.

The measure, approved Monday evening 8-3 by the Denver City Council, will become law if approved in the  final vote. It would apply to recreational and medical businesses.

The vote came after lawmakers failed to reach agreement last week.

If enacted, the new legislation would put a cap the total number of cannabis shop locations at their current level, and gradually reduce the number of cultivation operations by 15.  The proposed ordinance is intended to replace a temporary moratorium on medical and recreational businesses, which  is set to expire May 1.

Like the temporary moratorium, the permanent measure would ban new medical marijuana dispensaries and cultivation centers in Colorado.

It would also require cannabis business license applicants to put together “good neighbor” plans that spell out how they will perform community outreach if problems surface after a business opens its doors.

Luckily, (for some) license applications pending before the caps are imposed would still be processed under existing rules.
