cigarettes and stroke Smoking increases risk in black adults WARNING - Smoking causes stroke

There is no harm asking a question, even if it is repetitive or redundant

Recent former smokers who switched to e-cigarettes were more likely to be non-Hispanic white, have higher incomes, have higher tobacco dependence scores and view e-cigarettes as less harmful than traditional cigarettes

And although studies to date have had conflicting results regarding the potential of e-cigs to reduce combustible cigarette smoking in adults, the use of any form of tobacco product among youths is thought to be unsafe (25)

Once this time-lag has elapsed, the harms of smoking compared to never-smoking may reduce over time in absolute terms, due to changes in smoking behaviours (eg, number of cigarettes per day) or product toxicity
