CONCLUSIONS:Here we demonstrate that exercise enhances plasma THC levels in regular cannabis users. The lack of a fasting effect may reflect the modest duration of fasting used which was associated with only a modest increase in fat utilization relative to exercise. Overall, these results suggest that exercise may elevate blood THC levels by releasing dormant THC from fat stores. These data suggest the interpretation of blood THC levels in roadside and workplace tests might be complicated by recent exercise.
This raises further issues for the messy [but lucrative and expanding] business of drug testing is problematic – something I have spoken about elsewhere see: http://www.slideshare.net/JulianBuchanan/anzsoc-auckland-2012
