Supporters of the medical marijuana amendment say the warning is a scare tactic to keep people from voting for Amendment 2, which needs approval from 60 percent of Florida voters to pass.
Demings cited Colorado as a place where kids could get the drug via trick-or-treating.
But The Associated Press reported in 2014 that there have been no such incidents in Colorado. Voters in the state approved an amendment that made it legal as of December 2012 for anyone 21 or older to possess up to an ounce of marijuana for any purpose.
United For Care, the pro-medical-marijuana group funded by Orlando attorney John Morgan, pushed to get the issue on the Florida ballot. On its website, United For Care cited a new poll that showed that Amendment 2 has a 74 percent approval rating. The telephone survey of 800 likely Florida voters was conducted by Anzalone Liszt Grove Research between Oct. 17-20.
