Ecstasy has pros and cons and it is pretty much a case of 'everything in moderation.'

It is of course better to do it whilst you are young and have no real commitments to worry about. As for that party, I'd advise against doing it in China, not only due to stronger Chinese laws, but also the fact there's not really a subculture there that understands it; you're better off at a good European club where you'll have better tunes, access to water, can dance for hours without people thinking that you're some kind of weirdo etc. Try doing that around a Chinese club's VIP area, where chubby combover sporting men in suits drink Chivas and Green Tea with hired girls that are half their age... It just wouldn't seem right.

Very few people have actually died as a result of taking Ecstasy; as long it is real MDMA Ecstasy that you are talking about. However, the serotonin depletion and related issues from doing it too often aren't cool but... Most people then tend to grow up, get jobs, have babies etc.

As for social shaming... That's a problem with all you right wingy tabloid readers, lol. No wonder some of the best clubs in Europe have a 'no phone' policy; not just for protecting those who may have dropped a pill, but also for people that wish to express their sexuality without fear of being exposed etc.
