I'll add a data point, though it's almost entirely negative. I've been at Google over 10 years and have yet to come across a person using illegal hard drugs. I can think of three people with serious drinking problems. There's been a drinking culture (many offices have beer on tap), but I see that changing, as people are more conscious of the negative effects. A bunch of people use marijuana, but off-hours.
I haven't seen people seriously discussing stimulants (such as Adderall and modafinil) as performance enhancers; I've come across a number of people using these, but all in the context of diagnosed ADHD. I've also not seen anyone experimenting with microdosing LSD.
There's a surprising amount of openness and support for talking about mental health issues in general. I think this is a really good thing. The stigmatization we see in broader society is not actually helpful.
Obviously this is all my personal observation, but I think I would know; I definitely saw some serious drug use when I was in grad school at Berkeley.
