i just looked at one classification of drug and the number was 5-10% of the population.Some simple googling and little reading tells me that number would be 13 to 18%.

That's just one of the myriad of drugs that could have these effects. Hell, what does he mean by "alter your personality"? That's the goal of any psych med. Also, I am guessing he would want to throw those doing any illegal drug in there too. What about smokers and drinkers? Do we include anything that alters our personalities?
Maybe we say I could have exaggerated a little and we meet in the middle ground of 30%-35%.
Either way, the number of law abiding citizens effected would be greater than if we implemented a ban like Connecticut did. Instead of the 30% US population of gun owners who couldn't have a certain type of gun (but still could have guns for protection and hunting), under SC's plans we would have 30% of the US population denied access to any type of gun. Odd stance to have for a pro-gun guy.
