The influence of cannabis on human brain has advantages and disadvantages

Marijuana is a kind of drug plant that can lead to trance It has long been shown that long-term use of marijuana can lead to mental illness A new study in the UK shows that two main components of marijuana, one of which can cause mental illness and the other can be used to treat mental illness, restrain each other's effects on the brain Researchers from King's College in London and other institutions reported in the new academic journal general psychiatry literature that they studied two main components of cannabis, tetrahydrocannabinol and cannabinoids, making some of them Anesthetists took one of the substances individually at a time, then used MRI to observe the changes in their brain, and they were given some cognitive tests The results showed that tetrahydrocannabinol increased the activity of striatum and other areas of the brain, and weakened the activity of other brain areas As a result, marijuana smokers' response to less important external stimuli increased, while their response to generally important external stimuli decreased This also explains why smoking marijuana can make people trance, long-term smoking can also make people's judgment of various things confused, leading to mental illness However, it was also found that the effect of cannabinoids was to some extent opposite to that of tetrahydrocannabinol For some brain regions whose activity is impaired by THC, cannabinoids can enhance the activity of these regions The findings help deepen understanding of the mechanism of cannabis's action, the researchers said On the one hand, research shows the relationship between tetrahydrocannabinol and mental illness Nowadays, the increasing content of tetrahydrocannabinol in cannabis drugs in some places is a matter of concern; on the other hand, the research results also show that cannabis bisphenol may be used to treat psychosis, but more research is needed to be truly used in medical practice.
