The article itself doesn't address concerns of many commenters here about black market sales or smokers compensating, but it links to a British Medical Journal article that does. https://tobaccocontrol.bmj.com/content/7/3/281?ijkey=ae6159552047baa248cf162e7fb5ce73220af722&keytype2=tf_ipsecsha https://tobaccocontrol.bmj.com/content/7/3/281?ijkey=ae61595.... Here's summary: A range of potential concerns and barriers was addressed, including the technical feasibility of reducing cigarette nicotine content to non-addictive levels, the possibility that compensatory smoking would reduce potential health benefits, and whether such an approach would foster illicit (“black market”) tobacco sales. Education, treatment, and research needs to enable a nicotine reduction strategy were also addressed. The Council on Scientific Affairs came to the following conclusions: (a) gradually eliminating nicotine from cigarettes is technically feasible; (b) a nicotine reduction strategy holds great promise in preventing adolescent tobacco addiction and assisting the millions of current cigarette smokers in their efforts to quit using tobacco products; (c) potential problems such as compensatory over-smoking of denicotinised cigarettes and black market sales could be minimised by providing alternate forms of nicotine delivery with less or little risk to health, as part of expanded access to treatment; and (d) such a strategy would need to be accompanied by relevant research and increased efforts to educate consumers and health professionals about tobacco and health.
