If you are asking as in a general questions, I can only speculate as I am not a DR. But if you are asking because you actively take ecstasy, read up on what it does to you. The risks you are taking. You can take it many times with no side effects, then one day you are dead. And as I say to my children, How do you know it is ecstasy. How do you know what is in the pill. My son in law took it once, he is now registered disabled. Would you risk you life for one night a 'buzzing'?
