DETROIT Residents are concerned about people coming to Riverside Skate Park in Detroit and getting high using whippits.Its a skatepark. Skaters like Morgan are fed up with seeing hundreds of whippit containers tossed on the ground. The packaging on most of the canisters describes them as cream charges, used for whipped cream, dressings and other deserts. Theres hundreds, if not, thousands of these whippit canisters and Im seeing other paraphernalia and stuff. Theyre really trying to change the city up and do better but we still have people here who just come down here and do whatever they want, Morgan said.
