no, it wouldnt. the thing about tobacco is it is naturally bad for you. i know a lot of weed smokers like to tell themselves that cigarettes are the only bad tobacco. yes they add shit to it. tobacco is still cancerous and bad. and the reason it wouldnt happen with weed is that with cigs as i said they were already bad for you, and all that shit was put in before the fda had any crack down, and by then they had been so established in society and also as a multi billion dollar corporation with political ties. im basing that on nothing but my better judgement. i dont think weed is going to be legal so i dont think it is anything to worry about. and additives arent to make them deadlier anyhow, it is for lasting longer and addictiveness and the like. big tobacco may be evil, but their interest isnt in killing people, it's in making money.

also i dont know where this idea that if it was made legal the government would sell it is coming from. the government is not the us tobacco supplier it is private coporations.
