Legalize the Big Gulp

Bill Bennett notes the disconnect between the push to legalize marijuana and eliminate trans-fat and cigarette smoking from the public square.
For many years, health-conscious liberals have waged a deafening, public war against cigarettes. Smoking bans in public places like restaurants and bars have been enacted in states all over the country. Recently, New York City, New Jersey and several other cities and states have extended those bans to include the newest tobacco fad—e-cigarettes. Yet, when it comes to smoking marijuana? Crickets.
What explains this obvious paradox? Do these liberals think that marijuana is somehow less harmful than a Big Gulp soda or a bucket of fried chicken? It’s hard to believe that’s the case, given the vast amount of social data and medical science on the dangers of marijuana.
