Typical Health Canada/Big Pharma story line. 
Most MDs can't spell endocannabinoid let alone tell you about the researched backed, growing understanding of a key self-regulatory system, the ECS in our bodies.

Readers, do yourselves a favour and seek out better info.  
A good place to start is O'Shaughnessy's Journal - easily found online.
