prohibition started because alcohol was a huge problem back then world wide and a counter culture started against it. it turned out to be retarded? yes, but it made sense to sane people at the time.  the russian tzar owned the vodka business and made his people addicted to it. still dealing with the consequences.  the alcohol we evolved with was in lower concentrations that what is made nowadays.  not saying we should make alcohol illegal, but it makes absolutely no sense for weed to be illegal.
