A charity working with homeless people in Auckland, New Zealand unknowingly distributed candies filled with a potentially lethal dose of methamphetamine in its food parcels after the sweets were donated by a member of the public
Good luck getting the real thing. I could buy some normal candy and a roll of food-safe paper, and sell it for hundreds of dollars. Or add cyanide too, just to ensure the customer won't complain when it doesn't get them high.
Although the ADHD joke is spot on - ADHD gets treated with amphetamines, and straight up meth is used for the most severe cases (I myself am on dextroamphetamine for my ADHD)
