DENVER (CBS4) – Some estimates show that as much as 45 percent of marijuana sales in Colorado are sales of edibles.

And most edibles take the form of candy.

This Halloween will be the first in Colorado since marijuana became widely available in dispensaries in the state, and many parents are concerned as the treat-filled holiday approaches.

This week in Colorado CBS News talked to a mom named Lauren Jones about the dangers of marijuana-laced candy possibly making it into kids’ Halloween candy collection bags.

“If it’s not a name brand I recognize, like Snickers or Milky Way then it goes in the trash,” she told CBS4.

Often it’s hard to tell the difference between marijuana edibles and regular candy, and sometimes edibles have packaging that’s similar. Denver police recently created a video warning people about pot in Halloween candy.

“Long term, down the road, we don’t know the effects of ingesting these products,” Dr. Michael DiStefano of Children’s Hospital Colorado told CBS News.
