![]() High thoughts can impact anyone who has consumed THC, but they are more likely for some than others. ![]() This effect could help explain why early research on CBD has been so promising for brain related illnesses like alzheimers, addiction, and PTSD. Some research has shown that CBD may also increase blood flow to regions of the brain involved in memory processing, particularly the hippocampus. ![]() There is also some evidence to suggest that CBD has its own unique effect on cerebral blood flow. On the other hand, after chronic consumption of THC, preclinical research suggests that there may be reduced blood flow and neural activity in certain regions of the brain (especially the ventral and dorsolateral prefrontal cortex) and these alterations may be negative rather than positive. One important thing to point out is that while acute THC consumption appears to be correlated to increased cerebral blood flow and therefore to the alterations in the way we think, these changes in brain function are temporary. The cingulate cortex, which also showed high correlations between cerebral blood flow increases and self-reported THC intoxication, is believed to regulate the interactions between sensory information, emotions and pain. Researchers also noted the right hemisphere, which is associated with mediating emotions, was substantially more activated than the left. The insula, which is involved with sensory perceptions like taste and flavor, as well as mediating stress induced cardiovascular responses, also saw significantly increased blood flow. Given that the frontal lobes are responsible for all these important thinking skills, it’s hardly surprising that boosting that area of the brain with increased blood flow, and thus increased functional activity, would lead to some wildly different thoughts.īut the frontal lobe isn’t the only part of the brain contributing to high thoughts. High thoughts can impact anyone who has consumed THC, but they are more likely for some than others (Shutterstock) Normally, the frontal lobes are believed to be responsible for our level of wakefulness, as well as some very important cognitive functions like abstract thought, synthetic reasoning, organization of independent behavior in time and space towards future goals, sensory data processing, cognition, volition and initiation of motor activity. The frontal region of the brain showed the largest increases in cerebral blood flow after THC consumption, and is responsible for some key brain functions. In previous work by the same authors, cerebral blood flow was found to correlate more strongly with cannabis intoxication than even the amount of cannabinoids in someone’s bloodstream. They theorized that the behavioral and mental changes associated with cannabis intoxication may be connected to increased cerebral blood flow, and increased functional activity, of certain areas of the brain. In one study, researchers found that many areas of the brain had increased blood flow after THC consumption. One important impact from THC – the main psychoactive component of cannabis – is an increase in cerebral blood flow to certain parts of the brain. This leads to most of cannabis’ numerous effects on the body and mind. When we use cannabis, its many cannabinoids, such as THC and CBD, activate our natural endocannabinoid receptors. Why do we think differently when we are high? But they can mostly be attributed to the way that THC and other compounds in cannabis impact the brain. These differing thought patterns can be unpredictable in how they manifest for individuals.
