> Sure, but it's also a fallacy to assume that nothing bad can happen in the long-term just because it appears promising in the short-term. Ketamime has already been widely used for decades, in much larger doses than whats being discussed. We're not talking "short-term" here. > I was just making an example of a drug that happened to appear benign and promising, but have serious unforeseen consequences in the long term. Even that is a misrepresentation of the history of heroin. I guess it could appear that way if you take the Bayers advertising materials at face value (but hopefully you're not doing that). The dangers of opiates - and of morphine derivatives specifically - were well established by the time heroin was released.
