I dunno about other places, but in Europe the average dose in a single tablet is ~200mg. This is largely due to a stupid law in the Netherlands where getting caught with a single tablet got you a slap on the wrist, but getting caught with multiple would have them try to pin "dealer" on you. The result is that in the past 10 years or so, the average dose per tablet went from 30mg to 200mg and I've even seen pills of 270mg (we have free, anonymous testing labs). On the bright side, they are much less often contaminated with amphetamines and caffeine nowadays... AFAIK, the LD50 of MDMA isn't known, but as a frequent recreational user I can tell you that taking over 2000mg in a single night is definitely not common. I know a lot of people who use recreationally on a frequent basis, and none of them will go over 400mg on a night, and even 400 is considered pretty bonkers. Most folks who use every weekend are probably pretty new to the experience and haven't noticed the side effects when using more than once per month.
