Here’s how you can help smokers kick that butt

In the first study to tailor nicotine dosing based on smokers’ choices while trying to quit, the results suggest that most smokers who use stop-smoking medications can easily tolerate doses that are four times higher than those normally recommended.

According to a study, when smokers-who are trying to quit-are allowed to regulate their nicotine intake, it helps them kick the habit.

Led by the Queen Mary University of London, the research has been published in the journal Addiction.

In the first study to tailor nicotine dosing based on smokers’ choices while trying to quit, the results suggest that most smokers who use stop-smoking medications can easily tolerate doses that are four times higher than those normally recommended.

The author of the study Dunja Przulj from the Queen Mary University of London said: “Smokers determine their nicotine intake while they smoke, but when they try to quit, their nicotine levels are dictated by the recommended dosing of the treatment. These levels may be far too low for some people, increasing the likelihood that they go back to smoking.”

“Medicinal nicotine products may be under-dosing smokers and could explain why we’ve seen limited success in treatments, such as patches and gum, helping smokers to quit. A change in their application is now needed,” he said.

“Our findings should provide reassurance to smokers that it is okay to use whatever nicotine doses they find helpful.”

The new study examined 50 smokers in a tobacco dependence clinic in Argentina, and is the first in the world to try a combined approach of ‘pre-loading’ nicotine prior to the quit date, and tailoring nicotine levels based on patient feedback.

Participants started on one daily 21mg nicotine patch four weeks prior to their quit date. The dose was increased weekly by another 21mg patch unless participants reported adverse effects or did not wish to increase the dose, up to a maximum of four patches totalling 84mg/day. The dose was reduced by 21mg/day each week from one week after their quit date, until it reverted back to the standard dose (21mg/day) four weeks later.

Participants were advised to continue to smoke as they desired throughout the pre-quit period, and were offered additional oral nicotine replacement therapies.

The team found that:

-Of the 50 participants, 90% progressed to at least three patches, while 72% progressed to four patches.

-82% of participants achieved four weeks validated abstinence from smoking, and experienced no significant increase in withdrawal symptoms, including urges to smoke.

-Cigarette consumption, smoke intake and enjoyment of smoking declined significantly during the pre-quit period, and the intervention was rated as helpful and easy to adhere to.

-During the pre-quit period, the number of cigarettes smoked per day reduced significantly from 20/day at the start to 6/day by the quit date.

-The number of adverse effects increased as patch dose increased. The most common of these were nausea, followed by vomiting, but were mainly mild and well tolerated.

-Two participants rated their adverse effects as ‘severe’, both at the 63mg dose. One reported headaches, nausea and feeling faint; the other experienced nausea and blurry vision. Both reduced their dose back to 42mg/day.

-Only 6 per cent of participants dropped out of treatment and none dropped out because of patch side effects.

Professor Peter Hajek from Queen Mary University of London said: “Smokers are perfectly capable of determining which doses of nicotine they find helpful. There is no risk of dangerous overdose because nicotine includes an effective safety valve in the form of nausea.”

“Our results also suggest that one of the reasons e-cigarettes are so much more popular and potentially more effective than other nicotine replacement treatments is that smokers can adjust their nicotine intake according to their needs,” concluded Prof Hajek.
