Why is Ecsatasy such a dangerous drug to take?

For most people, its not the MDMA it's the things that are getting cut with that some people (don't know the exact figures off hand of the population that will take a bad turn on it) take an allergic reaction (sort of like if you use an Asthma inhaler and you don't need one or it wasn't prescribed for you), also a key factor to look out for of people who do take it is to drink plenty of water at least 1 pint of it per hour, try not to drink alcohol either or drink a lot less than you are of water.

That is exactly right. What makes Ecstasy dangerous is that Ecstasy pills are rarely pure Ecstasy (MDMA). Usually, they are cut with other drugs, and unless you have a pill testing kit, there is no way to know for sure what those other drugs are.
