I don't know the exact amounts that were tested but they look remarkably similar. The information here came from an chapter in _A Primer of Drug Action_. Another very informative book about MJ is _Drugs and Behavior an Introduction to Behavioral Pharmacology_. Both of these books provide an interesting discussion of the history and effects of MJ. Anyone else out there with info let me know.
