Moderators of the impact of e-cigarette provision on smoking cessation: secondary analyses from a large naturalistic randomized clinical trial in the US.
A large US trial found that providing e-cigarettes to smokers helped them reduce or quit smoking equally well across different age groups, income levels, and smoking histories. The benefits did not vary significantly based on who the smoker was—suggesting e-cigarettes may work as a cessation tool across diverse populations.
