In 2012 voters in Colorado gave approval to Amendment 64, legalizing cannabis throughout the state. Despite legalizing cannabis possession, cultivation and retail outlets, it retained the illegality of cannabis being consumed at public venues, even at privately owned businesses. That will soon change, however, as Denver voters have given approval to Initiative 300.
Initiative 300 allows cannabis to be consumed onsite at various adult-only venues. This includes bars, nightclubs and other such outlets. This gives cannabis consumers legal outlets to use the plant outside of a private residence.
