So I've converted a couple people to Vaping. My brother is full time. My friends son just started. But he is smoking less. Anyways.... a friend got interested in it today.... problem is, he only smokes when drinking. I feel that Vaping could get him hooked on nicotine more dependantly . Is Vaping a lot still better than smoking a little? With all the flavors.....and the hobby aspect....it's easy to get sucked in.
Great job on the conversions

. For your latest one, it's not so simple IMO.
He only smokes when drinking, but how long is that going to last until he gets sucked in and starts smoking full time? If that happens, he could still switch to vaping, but it's something to consider. Or, like other people have also said, he could just switch now to vaping when he drinks.
Personally and FWIW, I find nicotine from vaping is not addictive for me. I weaned down to no-nic over 9 months, vaped that for 6 months, vaped 10 mg (the highest I could vape then) for a month and then back to no-nic for a month. I had no problem whatsoever switching to no-nic the second time.
The current thought from medical people who understand vaping and have reviewed the best research we have on vaping is that the risk is around 1% that of smoking.
I would explain all this to him and let him make up his own mind. He is after all the one who is taking on the risk.
