For those of us who don't find spending money to light a plant on fire and inhale the fumes a good idea.
1. If you smoke or abuse recreational drugs, you will be banned. (this includes being a drug addict and using any form of nicotine)
If you are trying to quit smoking, you've come to the wrong place. Try /r/stopsmoking.
2. No linking to other parts of reddit. Screenshots must have censored usernames.
3. Vote, report rule breaking (as in invading druggies).
The best way to counter brigading is by upvoting content you like to see and downvoting/reporting people brigading/breaking the rules.
