Below the original comment in a reply is YouTube's full list. One of the items bans videos about "hard drugs" which it defines as any drug that causes a physical addiction. Is there an incoming wave of coffee- and tea-related takedowns? Because I'm pretty sure that headache you get when you don't drink caffeine for a day is not your brain longing for the rich aroma of freshly-ground beans. It's a physical addiction to ... a drug!
They should just make the rules say "We don't know what our standards are. If someone flags your video and whoever happens to be reviewing things doesn't like you, you're gone. Buh bye." At least people couldn't complain, as every takedown would comply with their written policy.
What about the premium series they produced, Mindfield? A good number of the episodes are about Michael Stevens (Vsauce) taking hallucinogens and describing the experience.
On second thought, I guess most of those aren't addictive. It still seems like a really odd line to draw.
I guess it depends on what Sergey or Susan are smoking these days... Odd throwing parties at 'plex when Prop 64 was approved, posing with joints, then banning drug videos...
