Please...there was so much misinfo in your post.
DO YOU KNOW ANYTHING ABOUT MDMA (i.e. ecstasy)
it can be responsibly used.
Just because you know people that have used it irresponsibly doesn't mean that it cannot be safely used.
As for the girl that snorted heroin thinking it was coke all I can say is that she is a complete moron.
Oh and as far as overdoses go from MDMA, they are few and far between. Most fatalities that involve MDMA are from the user not remaining hydrated or from some other secondary cause (like combination with another drug)
And I am sorry that your friend got raped at a rave, but she is an idiot for not preparing herself... i.e. she could have gone with people she trusted or not gone at all.
Why blame it on the drug?
FAR more people die from Alcohol abuse than from all other drugs combined.
