Tobacco industry would be all over this proposal, as people will just buy more cigarettes. As a thought experiment, raising minimum allowed nicotine contents up to a level where an average person experiences the unpleasant effects of mild nicotine overdose (dizziness and further) without long-term damage is what could actually force some smokers to quit, and more others to never start. That would be a very controversial measure, of course (and those with dedication would be willing to work around it by breaking the container).
