Marijuana business failure rate of 40 percent not bad, says industry expert

In recent days, the Denver Post reported that the number of medical marijuana businesses in Colorado has dropped by more than 40 percent since its peak at the end of 2010 -- from 1,131 to 675 over the course of fewer than three years.

That may seem like a precipitous slide. But one industry expert says that after weighing the various factors and challenges unique to the medical marijuana business, the decline isn't calamitous as it might appear.
