Cannabis Control Act

What is it?

Possession, manufacture or sale of marijuana.

What does our data show?

Much, though not all, of this law was made moot when marijuana was legalized in 2020, though police continued to make arrests for possession of more than the legally allowed amount or illicit distribution, according to The Chicago Reporter. The number of marijuana cases reached a peak of about 28,000 in 2007 — or more than 75 each day — before dropping by more than 80% in the years since. About half of the cannabis-related cases we found were for misdemeanor possession of 10 to 100 grams, while another third of cases were for possession of less than 10 grams. A 2016 law signed by Bruce Rauner that decriminalized possession of less than 10 grams of marijuana was followed by a decrease in low-level possession cases in Cook County.
