Just an interesting comparison of the two types of cigarettes.  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.
