So, I've read TFA, I see no citation, and I'm still Googling to track down the original research. They may not have made it up, but they may have taken it out of context or omitted details. >> Have you known anyone who hasn't had a problem with either of those drugs but still used them at some point in their life? No, I haven't. That's why I'm curious about whether the statistic is uniformly true, or averaged, or what. I'm not saying they made it up, I'm saying I'd like to see more details about how they arrived at that number. edit: for instance, let's say 90% of "drug users" are marijuana users. Okay, then I'm not surprised, but that would only speak to the danger of marijuana compared to other drugs. Or is it 90% of the users of any given drug? I'd be surprised about the latter. Coming from the United Nations is not a shining banner of truth and unbiased facts.
