Nicotine products relative risk assessment: a systematic review and meta-analysis

Titled “Nicotine products relative risk assessment: a systematic review and meta-analysis” the authors of this paper have developed a Relative Risk Hierarchy (RRH) of 13 nicotine products based on a systematic review of scientific literature and available evidence. Toxin emissions and epidemiological data of the products were analysed and combined on a scale from 0 to 100 (low to high risk) to deliver a combined risk score for each product. It comes as no surprise that they found combustible tobacco products had the highest risk scores. The lowest risk score products included electronic cigarettes, non-tobacco pouches and nicotine replacement therapy.
