- With all the talk about how bad cocaine is bad because it reduces cerebral
- blood flow (CBF)/ glucose expenditure, I bumped into some research that found
- cannabis increases CBF in the right and left frontal lobes and the left
- temporal lobe.
-
- This would be a good thing to throw at a drug warrior who claims cocaine is
- bad because it decreases CBF. (ask him, "does this mean that cannabis is good
- because it increases CBF?" -- of course it doesn't, but it's a good thing to
- know anyway..)

- Abstract:
- In experienced marijuana smokers, marijuana smoking was accompanied
- by a significant bilateral increase in cerebral blood flow (CBF)
- especially in the frontal regions and cerebral blood velocity. The
- post-marijuana CBF increase could not be explained on the basis on
- changes in general circulation or respiration. Similarly, the CBF
- increase was unrelated to plasma levels of tetrahydrocannabinol and
- extracranial circulation. Behavioral changes showed significant
- correlations with CBF. CBF and brain function are closely coupled and
- therefore it seemed highly likely that CBF changes after marijuana were
- closely related to its effect on mood and behavior.
