After two unsuccessful attempts to quit smoking, Jodell Kaiser paid a visit to Mayo Clinic and began using Varenicline, a drug that treats nicotine addiction. A study published in JAMA looked at a group of participants willing to quit smoking, assigning half of them to a placebo regimen, and administering Varenicline to the other half. Results of the study showed that after six months, patients who took Varenicline were over four times more likely to abstain from smoking compared to the placebo group. Furthermore, no adverse side effects were noted with either group.
