Actually a lot of drugs can be full of other toxic substances that are cheaper than the drug itself. One that you tend to hear a lot about is Ecstasy. I don't know how common it is, but I remember hearing that sometimes it could be full of stuff like rat poison, so if you wanted to score some you wanted to have a dealer you trusted, not just some random guy at a rave.
Completely agree, but my point is that even if you score it from a trusted dealer -- the so-called "pure" ecstasy you're getting is still dangerous to your body and mental state, even in the absence of additives.
MDMA does have known harmful effects. So does ethanol, and from what I can tell, ethanol is more dangerous. What would be your argument for maintaining a ban on MDMA and not banning ethanol[0], or do you believe ethanol should be banned as well?
MDMA is not harmful by any reasonable definition. It's possible for overuse to cause problems, it's possible for certain people with specific preexisting conditions to have problems. That's true for asprin as well.
