My 13 reasons to use it post-stroke.

Regular marijuana users have increased connectivity in their brains, despite having some gray matter loss in areas related to addiction, a new study finds.
The research, published in the Proceedings of the National Academy of Sciences, is the first to use multiple brain scanning techniques to examine both the structure and function of the brain.
Dr. Sina Aslan, one of the study’s authors, explained:
“What’s unique about this work is that it combines three different MRI techniques to evaluate different brain characteristics.
The results suggest increases in connectivity, both structural and functional that may be compensating for gray matter losses.
Eventually, however, the structural connectivity or ‘wiring’ of the brain starts degrading with prolonged marijuana use.”
The study involved 48 adult marijuana users who used the drug, on average, three times a day (Filbey et al., 2014).
They were compared to 62 matched non-users of marijuana.
The researchers found that the pattern of changes in both connectivity and structure of the brain depended on when and how often the drug was used.
Increases in connectivity were greatest when people began to use the drug and, the more they used it, the greater those increases.
