Each package of Nerd Ropes lists 100 milligrams of THC as an active ingredient, but it’s unclear how much was consumed by the concertgoers. One arrest was made, of Matthew Gross, 28, hailing from Ypsilanti, Michigan, who has now been charged with charged with a fifth-degree felony.

Needless to say, Gross’ alleged actions were incredibly stupid, as novice users of cannabis edibles frequently become overwhelmed by large doses of THC. While no one was permanently injured by consuming completely non-toxic cannabis, the incident created more bad press further demonizing edible cannabis products, giving ammo to prohibitionists.

While no one should go to jail for possessing cannabis, handing out THC-infused candy to unsuspecting people who may not realize what’s in it creates a dangerous and negligent situation. Pranking people or getting them high without their knowledge or consent is a criminal offense and should remain one.

If you’re trying to spread the love at a festival or party, always start with low-dose edibles and clearly inform your guests how much THC is in the food, lest anyone have an unpleasant experience. Dose responsibly and follow our tried-and-true advice on how to consume edibles properly for a fun psychedelic adventure, not a bummer trip to the ER.
