Colorado Clean Indoor Air Act
Protecting your right to #BreatheFreeColorado since 2006
The Colorado Clean Indoor Air Act has been protecting you and your family from secondhand smoke since 2006. Marijuana smoking was added in the law in 2013. The law does not include prohibitions on indoor tobacco or marijuana vaping.
