Most specialist smoking cessation services advise patients to select a quit date and quit smoking completely on that day (usually along with medication), but many smokers prefer the idea of cutting down gradually. What are the pros and cons?
I theory, cutting down gradually might provide a “softer landing” in that it might spread out the nicotine withdrawal over a longer period, rather than giving the nicotine receptors an abrupt shock of no nicotine. It also seems to fit with common sense that it might be easier to change the behavior gradually rather than all at once. Read more »

I was recently asked to review a new textbook on Nicotine Psychopharmacology, containing 18 very thorough chapters describing the latest evidence on the effects of smoking and nicotine on the brain and behavior. Much of it, though interesting, was a very heavy read. But it occurred to me that it might be useful to try to summarize what the 544 pages in this new book suggests about the effects of nicotine and the reasons smokers get addicted. So here is an attempt to describe how nicotine addiction works, in simplified terms.
When a smoker inhales nicotine from a cigarette, the drug is carried to the brain in highly concentrated form within around 10-15 seconds. The drug then Read more »

Across the country health insurance coverage for smoking cessation treatment – both counseling and medications – has been extremely patchy. For example, we ask all the new patients attending our smoking cessation clinic in New Jersey if their insurance covers smoking cessation treatment, and the vast majority have no idea. Typically its also not easy for either the patient or provider to find out either. It doesn’t just depend on the insurer, but on the plan, the type of service, what they’ve already had in terms of preventive care. We’ve had many occasions where we call the insurer twice on the same day and get a different answer. And New Jersey is a state that is supposed to have relatively good insurance coverage for tobacco cessation! So it’s a mess nationwide, and the net result is that fewer patients get the treatment they need because they are put of by the uncertainty about the cost and difficulty finding out how much it is.

Nicotine replacement therapies (NRTs: patch, gum, lozenge, nasal spray and inhaler) are intended to be used to help smokers to quit smoking completely. But an international report was recently published, finding that of the 17% of smokers who had used NRT in the previous year, approximately a third had used it for reasons other than quitting smoking.
The study was based on a survey of 6532 smokers in Australia, Canada, United Kingdom and the United States, and found similar patterns in each country. The patch was by far the most commonly used NRT (70%), followed by the gum. Overall, about 8% of NRT users had used NRT just to reduce their smoking, and around 8% had used it to help them cope in situations where they couldn’t smoke. The report stated that, Read more »

Nicotine withdrawal symptoms typically peak in the first week of abstinence and return to normal at around 3-4 weeks. It has long been known that certain nicotinic receptors (particularly the beta-2 subtype) are closely involved in nicotine addiction, and that smokers have a larger number of nicotine receptors in their brains than non-smokers. When the smoker quits, this large number of vacant, unstimulated receptors is believed to be involved in the resulting craving and distressing withdrawal (irritability, restlessness, depression, anxiety, poor concentration etc).
Earlier this year, a study published by Drs Kelly Cosgrove, Julie Staley and colleagues at Yale University, provided evidence on the time course of normalization of these receptors after quitting smoking. Read more »
