Marijuana Brain Adrian Assalve/CGinspiration via Getty Images

Human beings sometimes have a troubling inability to hold two thoughts in mind at the same time -- not only when the two thoughts contradict each other but even when they simply appear to be in conflict with each other but actually aren't. And nowhere is there a greater need for us to get past this tendency than when discussing the ongoing war on drugs. It should be possible to say that, as a first step toward ending this shameful chapter in our country's history, we should continue with the movement toward the decriminalization of marijuana. And we should also be able to say that as we decriminalize, we should take every step possible to minimize the harm, since there is scientific evidence of the dangers of pot on adolescents and young adults. So as we move toward legalization, let's put the science front and center.
