I am an oldie that keeps visiting this site as a matter of interest. (I'm 62)
I personally might take E some day, in very controlled circumstances. Both of my kids (now in their 20s) have experimented with E, but ONLY after educating themselves very thoroughly about it, and all the others -- and having it tested. It is always best to use it VERY sparingly, and they report positive results if so used.
Erowid.org is a good source of information, as is a book Ecstacy-- a user's guide. Also psychologist Alexander Shulgin are allsources of accurate information.
The biggest danger of taking this recreational drug is if you don't look after yourself and either get dehydrated and suffer heatstroke and die, or, at the other end of the spectrum, to counter heatstroke,you drink too much water and lose electrolytes which will cause the brain to swell and you will die.
It is also wise to have the drug tested. see dancesafe.org.
The biggest threat to your life comes from the US Senate, and their "Ecsacy Anti proliferation Act" This, in itself is probably doing an incredibly greater amount of damage to people who get caught than the extremely rare deaths. Viagra which is made specifically for "approved" recreational purposes by pharmaceutical companies with great lobbying power, has in its short life caused more deaths than Ecstacy, which has been around since the 1920's. Mind you, it's really not wise to mix viagra with E. That can kill you too, but some people do it. I guess if at a young age you cannot get a hard-on, you really should talk to a doctor.
Take care.
