Imagine the federal government decided one day that a doctor-prescribed medication you're using is now illegal. Imagine the government then sent you a notice demanding that you write a letter to them, declaring you have destroyed all your illegal medication. And if you don't, the government says they will pass your confidential medical information -- and that of everyone else using this drug who doesn't write a letter -- to the police. Improbable as it seems, this is exactly what's happening to more than 37,000 Canadians right now. And apparently the Harper government considers this acceptable, because the medication in question is marijuana.
