If anyone here understands the neuropharmacology of marijuana use and also the neuropathology of old age then could the two share similar traits? Apparently, we lose seven to 10 milliseconds -- a tenth of a second -- of brain speed per decade from age 20 on. The difference between a resourceful mind and senility is only 100 milliseconds of brain speed. We react to light in 50 milliseconds, recognize sound in 100 milliseconds, and think in 300 milliseconds. By the time thinking slows down to 400 milliseconds, we can no longer process logical thoughts. Relate this to how marijuana slows the processing speed of the brain and could the effects of marijuana be similar to the effects of old age on the mind only without all the creative, abstract thoughts and insights marijuana brings.

no cannabinoids are localized in a few particular regions, which though they affect stuff like short-term memory and mood, can't be compared to the broad and awful loss of function seen in dementia patients. you still know who you are, what year it is, and what you'e supposed to do tomorrow. now perhaps if you stack it with a bit of LSD and ketamine, the patient finally resembles the senile, but that's a detail
it also amazes me that speed could be measured in milliseconds. i prefer to measure it in mph, as in, when i went to grab bagels this morning my head was traveling 45 mph. someone's clearly a fast thinker and it's not necessarily related to my reaction time. a lot of my greatest insights come to me in a drunken haze
