So, despite our disagreements over what constitutes substantial harm, I'd still say Valg seems like the most qualified scientist Cf'er I can think of.

I'm curious, having read through a discussion on Dio's about the long term harm of marijuana use. I actually don't smoke pot more than maybe once every 2 years, but I would like to see the 'scientific' viewpoint of the validity of Heath's study and other subsequent studies and what the general scientific consensus of the topic is.

Looking to clear the fog, metaphorically speaking.

Anywho, sound off.
