When THC reaches the brain, it attaches to cannabinoid receptors, an action which kicks off the high. Studies have shown that it has a direct affect on one’s episodic3 memory, and can create difficulty in thinking and problem solving, among other issues. A number of studies have made a direct link between marijuana use in high school and subsequently lower grades as well as higher drop-out rates compared to non-users.4
More relevant to our topic, research has shown that long-term use can create the same kinds of physiological changes in the brain as other drugs.5 These changes are significant in determining the addictive capacity of marijuana, but they are not alone in supporting the conclusion.
