Heard one of the proponents for this from university of Colorado say it would remove the cost of enforcing the laws against marijuana. What nonsense ... Only a matter of time before a group forms called Mothers Against Driving with marijuana. The will work for laws that make driving under the influence illegal, systems will have be set up to test how much is too much, and laws made to send people to jail for breaking those laws. I don't like drunk drivers, Alcohol is legal, do we want to public endorse more people without their senses on the road or stumbling around our streets. Just what we need with a Pres in Wh who by his own writings apparently "did blow".
