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.
