I don't know if there are that many smokers who don't realise that quitting would be a good idea. How about getting these kids to educate people about what many don't know, like the ineffectiveness of the quack remedies, unnecessary dietary supplements, and allegedly miraculous weight loss products sold in practically every pharmacy alongside real medicines.

I've even had the manager of my local pharmacy forcefully try to up-sell me a bottle of herbal placebos based on the knowledge of my ailments she'd aquired from my prescriptions! Any pharmacist who permits the hawking of snake oil cures from their establishment ought to be defrocked, or whatever it is that's done to disgraced pharmacists; ceremonially stripped of their little label printer perhaps.
