Ecstasy/Talk

Moved to talk:

"Despite popular belief, the drug is not very deadly: the LD50? is 100mg/kg or roughly 70 standard quality clandestine pills. (LD50 is the amount of a substance at which half of those will take this amount will die.)

The dangers today is largely believed to be of a more mental aspect. Severe depression is regarded as the most evident."

Note that this could be taken to mean that 25% of those who take 35 pills or approximately 2% of those who take three pills will die. However, there is no requirement that the LD50 scale linearly - it could be 0.005% at three pills or 40% - there's no way to tell from the LD50 alone. Also note that the LD50 tells nothing about other side effects - a hypothetical drug might have an LD50 of 75 pills, but 80% of people who take even one pill are rendered permanently parapalegic.
