Denver Police and the Rocky Mountain Poison and Drug Center reported no cases of people slipping marijuana to unsuspecting trick-or-treaters.

Joe Hodas, of marijuana edibles company Dixie Elixirs, said the warnings were “overblown and ridiculous.” Parents should scrutinize their kids’ Halloween candy, but most people who use edibles are diligent about keeping them away from children, he said.

“We’re relieved but not surprised as to the results of Halloween,” Hodas said.
