DENVER — Two-and-a-half years after Colorado voters legalized recreational marijuana, activists are hoping to convince Denver voters to amend city laws to allow a private business to decide if consuming marijuana on their property should be allowed.

The group behind the 2012 passing of Amendment 64, which legalized marijuana for people twenty one and older, is hoping to collect enough signatures to force a ballot measure for the November 2015 in Denver. The measure, which is still being written, would essentially allow businesses like bars and restaurants to section off an area where marijuana consumption would be permitted.

“We allow adults to go to private businesses and drink socially, there’s no reason why we shouldn’t let adults do that with marijuana,” said Mason Tvert, a Colorado based marijuana legalization activist.

Denver’s City Attorney met with the group behind the measure on Wednesday and asked a wide range of questions over what and what would not be allowed.

“The thoughts of it being used in restaurant and bars in places where kids can see this, its very disturbing,” said Gina Carbone, a spokesperson with SMART Colorado. The group has been influential in creating marijuana policy with state lawmakers in regards to keeping pot away from children.

Organizers behind the measure hope to collect signatures throughout the summer in order to qualify for the question to appear on the November ballot. An awareness campaign about the proposal is expected to be released in the next several weeks.
