They do have cheesecake vapes! I didn't really care for the one that I tried, though..... Usually people will gain weight after quitting smoking, but I totally agree that vaping will satisfy your sweet tooth! And, I also think it is great for diabetics, they can vape sweets!
from what i understand, quitting smoking results in weight gain due to one or all of the following:
1. removing nicotine from your diet. removing nicotine not only slows your metobolism temporarily, but also eliminates the stimulant effect which reduces hunger.
2. hand-to-mouth cravings are satisfied not by cigarettes but by food
3. flavors become more robust after quitting, encouraging eating
None of the above problems are things that a vaper runs into, except maybe the third one. but like many have experienced, the stimulant effect of the nicotine eliminates deep cravings for food. so for the majority of us, while you did quit smoking, you havent quit nicotine. and only with the removal of nicotine do we start to experience difficulty. YMMV.
