E-cigarettes containing the drug varenicline and nicotine are effective in helping people quit regular cigarettes. This was reported by Health Day.
The experiment involved 458 participants (aged 25 to 75) who were daily smokers. Participants were divided into three approximately equal groups. The first took the oral medication varenicline and a nicotine-free e-cigarette; The second was oral placebo medication and e-cigarettes with a nicotine concentration of 18 mg/ml. The third group received oral placebo and nicotine-free e-cigarettes. To exclude the effect of self-hypnosis, it was necessary to use placebo drugs (without nicotine).
Researchers evaluated whether patients were abstinent from smoking by measuring their exhaled carbon monoxide levels. During the week, 43.8% of patients in the varenicline group, 40.4% of patients in the e-cigarette group, and 19.7% of patients in the placebo group abstained from smoking.
The results mean varenicline and e-cigarettes are effective in helping people quit nicotine addiction. It is noteworthy that all of the participants have been smoking for many years and have not been able to give up this habit after many attempts.
