Could you support the FDA regulating tobacco so that tobacco companies were required to produce different strengths of nicotine cigarettes to help wean people off smoking?
Smoking addiction costs our country billions in healthcare dollars. It is more addictive than cocaine. Is that reason enough?
I'm going to give a conditional "No", with reasons.
Personally, I don't trust the tobacco industry to make products designed to get people to stop using their main product. The conflict of interest combined with their track record of pursuing profits without any ethical concerns about the outcomes, to the point of hiding the results of their own studies if the results were unfavorable towards profits, makes this a bad idea, in my opinion.
Tax dollars, however, are much easier to work with. Taxes on tobacco are relatively high, almost exorbitantly so in some states. That money is supposed to go towards treatment and prevention of addiction, as well as helping to minimize public health risks involved with smoking (going from memory, I
believe this is accurate). I believe (again, not sure, going from memory) some of those tax dollars subsidize addiction-curbing products like gum and patches, this may vary by state though. I don't see why cigarettes with different grades of tobacco strength couldn't fit into that scheme.
Overall, while it might help curb the addiction, Vaping is probably a better alternative and much easier to adjust how much nicotine you get, without the physical damage caused by smoking. Nicotine doesn't cause lung cancer, smoke does, it doesn't matter if you smoke tobacco, weed, corn silk, or carpet fibers. Due to the presence of certain chemicals and additives, tobacco and carpet fiber smoke happen to be particularly carcinogenic. That being said, I understand some people simply do not like vaping and get no satisfaction from it.
