Re: Federal poll shows Canadians want marijuana laws changed, July 31. There has been considerable press of late on whether to legalize the sale of recreational marijuana. And both the Liberal and Conservative Parties have been playing to their respective bases concerning the issue. However, no one has addressed what appears to be a fundamental contradiction; how can one substance be at the same time a medicine (medical marijuana) and something that is intrinsically harmful and be banned? In my view, the only logical answer is legalization and control. Carl Raskin, Ottawa [end]
