CHICAGO (AP) — A marijuana company has proposed opening a cannabis dispensary on the same Chicago block as an addiction treatment center that serves about 500 people daily.

The dispensary proposed by NuMed would be on the second floor of a building whose entrance would be near Haymarket Center. Haymarket officials worry having a marijuana dispensary so close would trigger patients to relapse.

Alderman Walter Burnett admits he abused alcohol as a teen. He says he opposes NuMed’s efforts, saying he doesn’t want to be involved in anything that may cause people to lose their sobriety.

NuMed representatives couldn’t be reached for comment Thursday.
