The cannabis that was available for illicit purchase at the time of the Le Dain commission was in the order of 0.5% to 1% THC. That was the material that was supplied to us from seized material by the RCMP when we began our studies.
The current average for seizure material is between 10% and 15%. There have been isolated cases of concentrations much higher than that. Certainly I would agree that the concentration has increased at least tenfold, possibly twentyfold.
