legalize sale and taxation of Marijuana Production for Recreational Purposes

for reasons not clearly supported with acceptable proof of hurting humans, marijuana hasn't been legal for a long time. It is a really good recreational drug with effects on humans lesser than the widely available cigarettes and alcohol, check wikipedia http://goo.gl/FpVFD . Not a single person has died as a direct cause of it , and being able to tax it can greatly help the economy, and make way for other countries to accept it. All medical studies of it have been inconclusive of any serious bad effects and actually inform of various good effect of it.
