xantax, a drug to stop smoking

Theres this newer drug called XANTAX it is a drug to get people to stop smoking. It's actually kind of amazing because it blocks somthing in the brain that triggers them wanting to smoke. The people who use it don't want to smoke anymore while they are on the drug and smoking makes them sick. The only thing about this is there are a lot of side effects such as weird dreams, depression, etc. My mom is taking this drug, but the only other thing about it was when she used it the first time, as soon as she stopped she started to smoke again. I think the only way it works is if you truly want to stop smoking and do not have to rely on the drug to completely do the quitting for you.
