pretty sure MDMA is the pure crystals so not mixed with anything
It can still be cut with other stuff, many other chemicals can come in crystalline form. That said, 'pure' mdma crystals are less likely to be cut with filler than random pills would.
A fair bit of well executed political spin evident by some posters, but hey ho, whatever the government says is bad for us MUST be bad for us.
As someone who used a variety of substances and frequently for a decade, and knows dozens of others who have done the same, I have only heard of 2 instances of someone's life going to crap, and that was due to their own psychological issues, not unlike an alcoholic. Is alcohol also evil then?
My gf hasn't touched a thing and never would. She doesn't have a problem with my past, as she knows me, sees that it hasn't had a negative effect on me as a person or my life. I dabble maybe twice a year now, and she is fine with that, she knows I do things safely and properly, in fact I put my life less at risk than she does when she rides her horse. I am less at risk of harm physically than she is when she drives her car.
If she wants to try it, let her, it's probably the best one for her to do so with, due to non-existent physical addictiveness. Does she have an addictive personality? That would be more of a risk than the drug itself.
MDMA has a much better diminishing returns affect compared to other drugs, which can be cained ad infinitum. It takes time to top our your serotonin levels, and if she doesn't like hangover, then she will hate comedowns, which is usually what makes most regular users eventually stop later on in life.
