Isn't this highly related to the work you do? I'm a software engineer who's quite experienced with most drugs including LSD. I can't imagine LSD improving my work at all.

And if I would need to take drugs to be good at my job, I'd just quit my job. Even the long-term effects of the most popular drugs are largely unkown (e.g. there's a lot of debate about the neurotoxicity of MDMA). Let alone all the lesser known drugs. These people who try to get 'more out of their brain' might just as well be totally ruining them.
