What a great post. It perfectly illustrates what pot use does to one's cerebral cortex. I would say that if he had pot use, it was later in life, whereas yours was heavy and before 16.
SNIP They have discovered, for example, that individuals who start heavy recreational marijuana use before age 16—when the brain is still developing—may perform more poorly on cognitive or behavioral tasks involving the frontal cortex, such as memory, attention, and judgment, than those who don’t use cannabis or who started using it later in life. A recent paper that Gruber co-authored underscored these findings using results from a simulated driving test. Neuroimaging has also revealed changes in white matter, the neural fibers critical for efficient communication among brain regions, in early-onset cannabis users.SNIP
