How many types of ecstasy pills are there?

There are MANY different types of ecstasy and pills, and you can find a lot of information about the subject here erowid.org/chemicals/mdma/mdma.shtml
One of the most common mistakes and misunderstandings is that the color, shape, and size of the pill doesn't matter; this is false. The size, color, and shape is what makes up the different types of ecstasy. Different names and colors have different effects and feelings, but overall X feels the same (enormous amounts of pleasure, brighter colors, slowed down time, etc), but different pills have different effects.

Check this website for info dancesafe.org I do NOT promote anyone... I mean ANYONE to do any type of illegal drugs. But hey I have been there and done that. I would much rather someone be safe and cautious as to what they are taking than to just wing is and hope for the best (and possibly get something that is totally lethal).

Extasy pill contains a chemical called MDMA which is supposed to be it's main ingredient. Unfortunately, since extasy is not a legal substance there is absolutely no one regulating what goes into the pill. Technically, the pill can contain anything from MDMA to a multivitamin..(best case scenario). In the worst case, it can be laced with things like Piperazines, Meth-amphetamine, Dxm, Ketamine, MDEA, MDA...----NEVER HEROIN or COCAINE----- Usually there is more than one chemical mixed which makes it extremely dangerous due to effect it can have on your body....

The reason why people wind up in hospitals is because they THOUGHT it was Extasy they were taking, while in REALITY it was something very different.
