ETOH is water soluble, delta-9-tetrahydrocannabinol is fat soluble. Completely different in how your body interacts and process it.
Metabolism does not equate to metabolites. Metabolites are byproducts of how your organs are dealing with a specific chemistry.
Pot inferes with how the hippocampus process the recording of memory, specifically short term memory. Since learning is based on short term memory; Pot smokers, where stupid is made. Ignorance IS bliss.
@cato:
Correct, if you have organ problems, the processing can take longer depending on which organs/chemical combos your talking about. When you drink, ETOH permeates all body tissues, even your knee caps.
