Which legal drug which you rather make illegal-alcohol or tobacco? Personally, I would ban tobacco and temporarily ban alcohol until breathalyzers can be installed into every single car in America. Basically, I would ban tobacco and keep alcohol legal, albiet with very string laws making it a federal crime to be drunk, because even if all cars had breathlyzers in them, people commit many crimes under the influence of alcohol, and being intoxicated with alcohol would be a federal crime. But I would keep alcohol legal. Tobacco is toxic to health! I would ban it!
