Here's a question for you:
Imagine you are seated at a table with two bowls in front of you. One contains peanuts, the other tablets of the illegal recreational drug MDMA (ecstasy). A stranger joins you, and you have to decide whether to give them a peanut or a pill. Which is safest?
You should give them ecstasy, of course. A much larger percentage of people suffer a fatal acute reaction to peanuts than to MDMA.
Enough time has finally elapsed to start asking if ecstasy damages health in the long term. According to the biggest review ever undertaken, it causes slight memory difficulties and mild depression, but these rarely translate into problems in the real world. While smaller studies show that some individuals have bigger problems, including weakened immunity and larger memory deficits, so far, for most people, ecstasy seems to be nowhere near as harmful over time as you may have been led to believe.
*Of course even if the adverse consequences of taking ecstasy (something I've never done myself, incidentally) were much more apparent there would still be little reason to prohibit people from taking an informed choice as to whether or not they wanted to use the durg.
