E-cigarettes have had some quality-control issues. Plus, most e-cigs contain addictive nicotine, and carcinogens have been found in some e-cig vapor. How about we get some more research and regulation up in here?

More than 10 million cigarettes per minute were smoked around the world every single day in 2016.
The Tobacco Atlas. Consumption. https://tobaccoatlas.org/topic/consumption/. (**Internal calculation - cigs smoked/min daily for 2016 is 10.8M : 5.7 trillion smoked in 2016, 5.7 trillion/365/24/60 = 10.8M per minute)
Cigarette companies advertised "light" cigarettes as less harmful to the smoker, although they can deliver the same levels of tar and nicotine.

Nicotine reaches the brain 10-20 seconds after smoke is inhaled.

Because nicotine from smokeless tobacco is absorbed through the mouth, it takes longer to produce an effect than if it were absorbed through the lungs. But using cigarettes and smokeless tobacco really do result in the same amount of nicotine intake.

Adolescents who use smokeless tobacco are more likely to become cigarette smokers.

An average of 4.5mg of nicotine is absorbed from 7.9g of chewing tobacco and an average of 3.6mg of nicotine is absorbed from 2.5g moist snuff.
