I agree, I had a friend who was getting ready to come off methadone and the sheer thought would make him sick and break into cold sweats. He was puffing on a cig-a-like to calm his nerves and I was like "Dude..." handed him my SX mini with a Goblin attached, he took a puff, and was like "Oh yeah!!"So in my opinion if it helps reduce those kinds of behaviors in even the slightest way while its technically not the same as starting to quit smoking it's still reducing harmful behaviors which is what vaping was originally meant for.
To make a long story short, I let him borrow my IPV mini and Lemo and gave him a crash course on how to rebuild. vaping literally took his mind off the withdraws and calmed his nerves. He has been clean for about two months now and has not had any problems. He has also become one of my best juice customers..hehe
