Tainted pot sickens 4 By KIM BRADLEY, Toronto Sun A batch of bad dope making its way through schools in York Region has prompted a police warning to pot smokers. Four high school students in Newmarket, Aurora and King City have become violently ill after smoking marijuana since Jan. 7. "And it stands to reason there are more incidents happening that aren't being reported because it deals with illegal drugs," York Regional Police Const. Stuart Betts said. The first case involved a 15-year-old boy who smoked a marijuana joint on his lunch break at a Newmarket school on Jan. 7. Shortly after, he began vomiting and kept losing his balance. He was treated and released in hospital the same day. Two days later, a 15-year-old King City girl was treated at the hospital after she smoked some pot and started vomiting blood. There have been two other cases reported to Street Beat officers working in schools in York's 1 District -- the most recent on Feb. 20, Betts said. The symptoms include vomiting, and loss of limb control, balance and consciousness. Police may never know what's in the tainted pot. "It could be anything from pesticides and fertilizers to herbicides. The people who are producing it and supplying it don't care about the health of the end user. There are chemicals all over the place in these hydroponic labs," Betts said. -Nickers - Comments anyone?
