The Proven Positive Effects of Nicotine and Tobacco


In 1994, Jacob Sullum told the following story at a Cato Institute seminar on tobacco use:

“A few years ago when I was working on a story about the antismoking movement for Reason magazine, I interviewed Scott Ballin, chairman of the Coalition on Smoking or Health. I raised the question of why people smoke. ‘There is no positive aspect to it,’ he assured me. ‘The product has no potential benefits.’ Not everyone concurs with that assessment; in a recent column in Vanity Fair, for example, Christopher Hitchens wrote that ‘cigarettes improve my short-term concentration, aid my digestion, make me a finer writer and a better dinner companion, and in several other ways prolong my life.’”

Disparaging tobacco’s value is a familiar theme with tobacco prohibitionists. They claim that the substance is worthless, and that the beneficial effects reported by smokers are only symptoms of relief from nicotine withdrawal. But smokers believe that they derive specific benefits. Who is telling the truth?

A meta-analysis just published in the journal Psychopharmacology reviewed the effects of nicotine and smoking on aspects of human performance (abstract here). The lead author is Stephen Heishman, a scientist at the National Institute on Drug Abuse; he is joined by Bethea Kleykamp of Johns Hopkins University and Edward Singleton of Stevenson University. The study will not please anti-tobacco extremists.

Heishman et al. reviewed 15 years of published studies on the effects of nicotine and smoking on various measures of human performance. They had strict criteria for the studies they accepted; one of the most important was including only nonsmokers or smokers who had not been deprived, in order to eliminate the confounding effects of withdrawal on performance.

Heishman et al. found that nicotine and/or smoking produces positive effects involving fine motor skills, attention and memory. The investigators conclude: “The significant effects of nicotine on motor abilities, attention, and memory likely represent true performance enhancement because they are not confounded by withdrawal relief. The beneficial cognitive effects of nicotine have implications for initiation of smoking and maintenance of tobacco dependence.”

It’s time to be honest with the 50 million Americans, and hundreds of millions around the world, who use tobacco. The benefits they get from tobacco are very real, not imaginary or just the periodic elimination of withdrawal. It’s time to abandon the myth that tobacco is devoid of benefits, and to focus on how we can help smokers continue to derive those benefits with a safer delivery system.

It is time! I'm glad you wrote this. Smoking (now vaping) improves my day in a myriad of ways. It irks me that non-smokers look at me and think, and sometimes say, "idiot." Yes, I have an addiction. It happens to be one with positive benefits. Perhaps more positive than negative in the short-term and maybe in the long-term if I am lucky. If it did nothing and was worthless except for having to maintain the habit, I would most assuredly quit.

Thanks for the article. Would it stand to reason that the positive nicotine benefits can be administered via nicotine supplements instead of smoking? or is there other chemicals in cigarette smoke that enhances creative performance/memory/attention? Nicotine increases the release of dopamine and serotonin - a lack of dopamine or serotonin is a common cause of depression.

The problem with smoking is the delivery system ie. smoke. Smoke from cigarettes is harmful and have been clinically tested to show an increase chance of developing cancer across the board.

I was a smoker for 25 years, and stopped about 15 years ago using the Nicolette gum. Alas , I have been chewing the Tim's for 15 years! I recently purchased an ecig, because I would really like to stop chewing the gum, because it is so expensive. I spend 6 to 700 a month on these. I am trying to determine if the ecigs are worse for you than the gum, and can't find an answer. Does anyone know?

Just remember that commercialized tobacco is not pure nicotine. There are many chemicals added in the production that does not occur in the tobacco plant naturally.

There are NO positive effects to smoking. There is a laundry list of negative effects, too many to list. Smoking is a sure way of getting a disease, cancer and killing yourself as form of slow suicide. The smoking industry want to sell products and dont care about health or protection of customers and it is a front if they say otherwise.
As a scientist and fitness instructor I am strongly against smoking and any thing that suggests that says it is not as lethal as it actually is.
