Cigarettes with very low levels of nicotine may reduce addiction without increasing exposure to toxic chemicals, according to a new study from the University of Waterloo.
The study published in the journal Cancer Epidemiology monitored the smoking behaviours of 72 adults as they switched to three types of cigarettes with markedly reduced nicotine levels.
Unlike when smokers switch between conventional cigarette brands—all of which have very similar levels of nicotine content—the study found no change in participants’ puffing behaviour, number of cigarettes consumed or levels of toxic chemicals in their systems.
The landmark findings may ease concerns that smokers would increase their consumption of cigarettes or puff harder if governments reduced nicotine levels to negligible amounts.
