Smoking cigarettes is dumb as shit because there are literally no benefits from it apart from satiating an addiction that you got from smoking in the first place. While I don't do drugs myself I can understand why people do. They generally provide a good and unique feeling and it's up to the user whether the trade-off of risks/side effects is worth it. I used to be pretty heavily into drugs myself and I'd be lying if I said I'm not tempted to go back sometimes, but it just wouldn't work well with my healthy lifestyle. When I'm old and decrepit, I'll be tripping balls 25/8.
