Please help me find support to the following arguements?

I don't have any links, but you might want to look up what happened during prohibition. The banning of alcohol at this time caused a black market to rise, and much of the "alcohol" made during that time was of course not regulated, and was tainted and made a lot of people sick. Also, more people, not less, drank during prohibition because times were rough. The number of alcohol-serving establishments also increased dramatically.
