(At that time, Juul, the highest seller in the United States, was not available in the US Juul had a much higher concentration of nicotine – 59 milligrams or 35 milligrams.)
All participants had an individual attitude within their study groups to get closer to real-life scenarios. When vapersi finished a bottle of nicotine fluid, they could choose any taste and strength of nicotine to buy it.
People who use nicotine replacement therapy can choose from a range of products, including patches, gums, lozenges and nasal sprays. They were balanced to encourage a combination them; most have done so, usually opted for patches and oral therapy.
Since confidence on smoking abstinence is not considered reliable, scientists have measured the amount of carbon monoxide in the breath of participants, more accurate validation.
Dr. Maciej Goniewicz, co-author of a British study, who is now a pharmacologist at the Roswell Park Comprehensive Cancer Center in Buffalo, New York, said the success of e-cigarettes most likely reflects a combination of factors:
"This is the way of delivery, the amount of nicotine and the behavior of the user," he said. "E-cigarettes have the advantage that the user chooses how and when to puff." Nicotine replacement medicines have specific guidelines that vary from product to product.
Dr. Benowitz noted that higher rates of cessation and compassion among e-cigarette users can be further explained as these subjects expressed greater satisfaction with the devices than the other group with their products.
In her editorial, Mrs. Dr. Borrelli and O'Connor pointed out further research on smoking cessation: In one study nicotine replacement therapy and buproprion antidepressant (Wellbutrin) achieved a slightly higher abstinence rate than e-cigarettes in this last study. The medicinal form of varenicline (Chantix) showed even slightly better. In addition, these products were proven safe, they said.
