I used to do plenty of drugs, both for fun and as a way to help my sleeping problems.
A little cannabis in the evening does wonders for your sleep and made watching Voyager and dumb reality shows before bed a lot more interesting too :)
xtc in the weekends while going clubbing. Pure fun and helped me with social anxiety.
Tried mushrooms a few times, too much hassle and side effects.
Cocaine, didn't really do anything for me and I didn't like the risks.
Speed, makes your dick shrink, no thanks. It was one of my most productive nights coding though.
Playing video games on cannabis usually leads to disaster or boredom. Some exceptions, playing adventure games while high was awesome. Totally immersed in Riven (following a walkthrough) and monkey island games. Watching movies however is great.
Since I moved to a small town in Canada (from Amsterdam) I had no access anymore. I didn't really miss it. Playing loud 90's hard trance still brings all the feelings back :) Nowadays I hardly ever drink alcohol anymore either. I prefer to wake up headache free with screaming kids around.
Games are my nr 1 drug now. Plenty of time for those as I still don't fall asleep before 3am. Plus endorphins from working out. Yet I wouldn't mind having a coffee shop around the corner again. You don't need VR for better immersion, cannabis does it too.
