WTA is expensive. I used it mainly to get over the hump of quitting and I keep a tank of it around for stressful situations.
Halting WTA is infinitely easier than detoxing from cigarettes though. With that said, TAR itself has been shown to have cerebral effects in the brain, actually, so even using WTA you will still be detoxing. There are various ways to handle that and I found WTA to be REALLY useful. I wish I hadn't started the husband on it, as I thought he'd dual use for a long time, but he recently came home with the loose tobacco equivalent of two cartons so now I wish I'd waited. LOL. I will not be buying him WTA forever, though. That ain't happening.
If you use it, use it strategically. Some folks prefer vaping it in an ongoing way and the alkaloids do provide some relaxant and antidepressant effects. Even if using it forever, my understanding it is safer than smoking but mainly due to combustion issues. If you never stop using it though, you may find yourself dependent on WTA over the long haul, as you will have never fully weaned from the alkaloids. Still less terrible than trying to give up cigs completely, but the alkaloids do play a major role in the "satisfaction" from cigarettes, however.
