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..)

after smoking marijuana. _Life Sciences_. 52(8):757-767.]

|
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.
