In recent years, federal agents and other law officers have been seeking to shut down so-called "marijuana candy factories" that create "enhanced" snacks supposedly for medical marijuana users. In some raids, they have confiscated thousands of marijuana-laced candies and soft drinks, including candy bars, cookies, marshmallow pies, ice cream, peanut butter, jelly and Rice Krispy Treats®.

"Some of these factories may think of themselves as legitimate," says Ortega, "but when you look at their 'line of products' you can see there's some serious marketing to children being done."
