What a tragic article. We can sell our soul and change our name to Faust.  Gary is there any limit to what you would do for money? Gary did you stop at marijuana?  Obama stated he didn't so maybe it is a gateway drug. You say the majority do not go on to harder drug, but that could just be 501 out of a 1000. So what about the other 499? What marijuana does is deprive the user of ambition.  I'm sure we all know people to who that applies. If you talk to the police officers in Colorado they will tell you that crime is up.   Esp. burglary and theft, in order to get money to buy dope. People follow UPS and FEDEX to take the parcels they deliver. Another thing which has gone up is homeless. People moved to Colorado for dope without any plans of supporting themselves.  Do we need to double our homeless population? They have an increase in deaths because of dope, including kids. The tax money will be all spent plus more on social services. Be careful of biased studies that have an agenda.
