I don't vape, but I have several friends who do. One of them gets really into it - he has over 100 vials of flavors & mixes his own liquids, cleans right down to the coils regularly, and so forth. This dude, btw, drinks daily, so it hasn't impacted his alcohol experience.
As a friend of 'vapers,' I think it's fan-freaking-tastic! Finally, we can all hang out and I don't have to smell like cigarette smoke. Please, for the second-hand sake of your friends, switch to vaping! Even if they proved tomorrow that smoking doesn't cause cancer, I would still encourage vaping because almost no one wants to smell cigarettes.
