For example, taking longer, deeper puffs will allow more nicotine to enter your lungs compared to quick, shallow inhales
If smokers adapt their behaviour in order to achieve the same amount of nicotine as they would get with an unventilated cigarette, they will thus take in more of the other harmful substances
There are presently more than 34 million cigarette smokers in the U.S., however, this number is down from 40 million in 1997
In addition, our results were still significant when we compared the non-age-matched groups, including younger patients who smoked marijuana and who presumably had less lifetime exposure to cigarette smoke. According to the CDC, 48.2 million people, or about 18% of Americans, used marijuana at least once in 2019
