I started smoking because I was a head taller than everyone, and I wanted to stop growing, I read in an article that smoking stunts growth, so I started smoking hoping that side effect was true.
I ended up addicted, with breathing problems and more.. and 32 years later found vaping as a way to get off the smokes.
Vaping is less harmful than smoking, but it is not without its own harms, many of them we don't yet know.
Basically, your coating your healthy lungs with an oil product..
So that what? Your cool? Smoking never made me cool, and it didn't stunt my growth either..still tall.. all it every did was make me sick..
If your friends don't like who you are, for who you are, they aren't worth being friends with.
Back in the day there was a certain weed people liked to smoke, and I never did partake, but the people I hung around with did and they totally respected that I did not, and they passed the funky weed past me when it came around the room.. totally cool, because they liked who I was, and I liked and respected who they were.. no questions asked.
If you are trying to get in with people who don't like and respect who you are, without coating healthy lungs with oil products, or anything else that they enjoy doing, then seriously, find some better people to be friends with.
That's my noob advice.
