Like I said in the original comment, I'm not trying to discredit anyone or even this particular study. I'm simply seeking a more deliberate model of transparency. That also goes for studies who may claim that marijuana is healthy or "less harmful" than other products.

This guy has over the course of several years come up with very damaging evidence that marijuana is irreversibly harmful to humans. To start with, to know who these studies are funded by would be helpful so I can know whether it deserves my attention.
