A new ordinance under consideration in Denver could make even the smell of marijuana illegal.
Colorado legalized recreational pot use for adults 21 and older last November, and retail shops selling marijuana will open their doors for the first time on Jan. 1, 2014.
However, Denver's mayor and city council want to make sure public pot consumption doesn't become a problem as a result.
The ordinance introduced Monday would ban marijuana from parks and the Mile High City's 16th Street Mall. It also would prohibit smoking on private property if it is visible to the public, such as on a front porch or in a car, or if the odor of pot could be detected from a neighboring property, the Denver Post reported.
"Your activities should not pervade others' peace and ability to enjoy," Mayor Michael Hancock told the newspaper. "Marijuana is one of those elements that can be quite pervasive and invasive. I shouldn't have to smell your activities from your backyard."
Offenders could face a fine of $999 and up to a year in jail.
The American Civil Liberties Union of Colorado called the ordinance a "tremendous overreach" and said it was unconstitutional.
