Nicotine patch might be cheaper but these aren't people who want to quit smoking, most of the vapers I know just do it because they don't want to smoke as much tabacco (save money because a pack of 20 costs €9.40) but still want something to do with their hands and get a slight buzz out of it. I know a few people who took it up as a way to avoid having to go outside every 10 minutes when they wanted to have a smoke in a pub (Ireland banned smoking in the workplace). Last week a classmate of mine was thrown out for vaping in a pub, hilarious to see him try to argue how it wasn't harmful, fucking idiot still hasn't learned that when a bouncer wants you out you can't argue.
