Ban cigarettes and trans fats -- but legalize marijuana?

The very same year, for example, that Colorado legalized marijuana, the Colorado Senate passed (without a single Republican vote) a ban on trans fats in schools. Are we to believe eating a glazed donut is more harmful than smoking a joint? California has already banned trans fats in restaurants statewide, but now is on the brink of legalizing marijuana statewide come November. Former New York City Mayor Michael Bloomberg supported New York Gov. Andrew Cuomo’s effort to decriminalize marijuana in New York State, while at the same time supporting a ban on extra-large sodas. A 32-ounce Mountain Dew is bad for you, but pot isn’t?

The logic is dumbfounding. 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.
