The majority of Michigan voters agreed to allow marijuana to be used as medicine in this state.

Thousands of patients have signed up to smoke, eat and drink the essence.

But, apparently, the Medical Marijuana industry is being built on anecdotal stories and lab tests. 

The Detroit Free Press says nobody has done a real-life, long-term study about the effectiveness of dope as medicine.

Now the University of Michigan is using a $2.2 million federal grant to track 800 licensed medical-pot users to see if pain relief can be quanitified and if there are side effects from long-term drug use.
