Apparently this thread exists. Well, while I'm here I might as well add a few more examples...
During the Ratcatchers quest, Smokin' Joe in Keldagrim asks you to help clear out some rats in a hole near him. The way you do this is to put some farming weeds in a pot, light the pot, inhale the smoke, and blow the smoke into the rat hole. Strictly speaking, ordinary gardening weeds aren't a drug, but think about it: pot, weeds...
In the Lunar Diplomacy quest, you enter the Dream World by burning a potion-soaked kindling and and inhaling the fumes. Sounds pretty drug-like to me!
This one's notable because it involves a real-world drug: In the Recruitment Drive quest, one of the items you can find in Miss Cheevers' room is a vial of nitrous oxide (a.k.a. "laughing gas" ). It serves no purpose during the quest, but you can choose to inhale it and get a short laughing animation.
(Yes, I'm somewhat of an expert on drugs in RuneScape. Don't judge. >.> )
