Second off, neither nicotine gum nor ecigs / vaporizers are designed to do anything other than deliver nicotine. Gum has been approved because the manufacturers did studies to prove that it could be used to aid cessation, then received FDA approval to advertise this use. Vaporizers have not been approved because the many and sundry manufacturers haven't bothered -- instead of saying "use this to quit smoking," they tell you why their product is so much more awesome than smoking.
Same result, different approvals and advertising.
So, again, there is no difference, pharmacological or functional.
I think they work great. Certainly a better alternative.
Started off with those blu ones.
Graduated to using a full vape, rocking one of these bad larrys now.
I must say...no more coughing. I feel 10X better (might be in my head).
" May you live as long as you wish, and love as long as you live"
Unfortunately, the draw was so stiff that I could never get enough in one drag. The part of my brain that was fiending for nicotine started putting out "I'm suffocating" vibes -- so instead of satisfying the craving so I could go back to work, I got panicy. Didn't even make it through the day before I had to break out the emergency pack.
It wasn't until I went with an actual rig with a much easier pull that I found my new home.
