Well, I was unable to take that, I had hallucinations.
However, for many people, not just for quitting smoking but for depression, etc. it works great and there are a great many people who CAN take it. My doctor said it is so mild that he can prescribe it for his pregnant patients.....it's an older drug w/proven efficacy.
The strange visual effects I got while taking it are, apparently, rather rare, but it IS in the literature. My doctor only had one other patient who ever had these visual effects so I guess I am rare.
Every thing you do is going to have "some" kinda side effect. I am not at all completely blind to fact that I don't believe inhaling food flavorings into the lungs is as good as breathing fresh air, and we do not know what the future holds for 2 or 3 decades of doing such things. That is why I consider vaping as harm reduction but not harm free. I certainly would not vape if I had not been trying to quit smoking.
That is why prescription drugs often help people stay alive, change a behavior, or possibly, harm them. It can go many ways. There is risks involved and everybody should weigh risk/benefit to their individual profile.
I just had eipidural shots in my spine, my herniated disks were just hurting so bad, to point of interferring with my daily living and ability to drive, etc. I was very scared, there are a ton of bad things that can happen once you have your spine "punctured" like this.
However, I received about 85% relief from my sciatica and pain, so I can get back to hiking and swimming and thankfully, nothing "bad" happened to me from having the procedure.
They make you sign this paper with a long list of all the things that can go wrong though. You have to make these decisions. MOST people have no problem.
