In some cases amongst chronic users, at least in the case of the studies, there are rather high THC levels 24 hours or eight hours after the fact. I note that your report says that with regard to these per se limits, the detection of THC would be well beyond the period during which they would be expected to experience acute intoxication. Later, it refers to zero to six hours after smoking cannabis as the time period in which there is really an acute concern about impairment. Is that correct?
