Compare this with Zyban or Chantix, used by only 12.2% of smokers trying to quit. Vaping is more than three times more popular than FDA-approved medications. While vapers can instinctively scoff at the use of smoking cessation medications, they undeniably work, increasing their likelihood of quitting smoking two to three times as compared to a placebo treatment.
Nicotine replacement therapies also increase their likelihood of quitting, and are widely available, but only 25.4% of smokers used them. Unlike vaping, the authors did not separate them into attempts to reduce and attempts to abandon altogether. Overall, evidence about NRT suggests that they are effective around 8% of the time - not much, but still better than going cold turkey.
