Really? And you know that, how? Documentation? I've known many pot users whose memories are poor to bad (small sample, but they all have memory problems--can memory loss be a possible consequence?). Is it paranoid to imagine there is a big conspiracy against pot users? Just asking...
It's sarcasm. I think there are consequences good and bad for everything we do, and pot is no exception. I was poking fun at people who never admit even mildly bad consequences for pot, and who vehemently reject even published peer reviewed papers that suggest any level of harm from pot smoking.
