HUFFINGTON POST: President Barack Obama plans to take questions from YouTube viewers Thursday afternoon, and for the third time in as many years, the overwhelmingly most popular query involves the legalization of marijuana.

Somehow, two questions about clean energy made their way into the top 200.
