«What if we thought of nicotine more like caffeine?» Very imprudent statement. Some certainly would like to see it that way. What they don't want to see is that nicotine can make you addicted for years or for life, including children who are now tempted to vape. Or am I wrong, can all nicotine users (smokers and vapers) quit instantaneously, without withdrawal symptoms? Then I must adjust my knowledge of nicotine addiction physiology. And then the revenue model of the tobacco and vape industry must also be revisited.
