Suddenly and totally banning tobacco products would have "scientific integrity" sure, but is practically impossible due to how human beings work.
However, tobacco is actually being gradually phased out across Europe. Compare smoking prevalence in a city now vs 20 years ago. Extrapolate out another 20 years.
My point is that the current regulatory approach to GMO lacks scientific integrity, and is anachronistic and hypocritical.
Alcohol can be justified as having some cultural merit, and there are many people who use it moderately. Tobacco is just making money from nicotine addicts while they kill themselves slowly. No need to ban it outright, just double the price every few years.
