Reducing smoking does not reduce deaths like quitting smoking
Inoue-Choi M, Christensen CH, Rostron BL, et al. Dose-Response Association of Low-Intensity and Nondaily Smoking With Mortality in the United States. JAMA Netw Open. June 3, 2020;3(6):e206436. doi:10.1001/jamanetworkopen.2020.6436
In a prospective cohort study of 505 500 nationally representative US adults, daily smokers had 2.32 times higher mortality risk, and lifelong nondaily smokers had 1.82 times higher mortality risk, than never smokers; significant associations were observed for 6 to 10 cigarettes per month and increased with higher-intensity use. Risks decreased when smokers reduced from daily to nondaily smoking, yet the benefits of cessation were far larger.
