Ontario researchers have done a study on laboratory rats that shows inhaling THC vapors from marijuana caused a schizophrenia and psychosis effect on their brains. THC is the chemical in cannabis that causes the high and hallucinations people experience. Neuroscientist Jibran Khokar and his team used eight lab rats implanted with brain electrodes for the experiment.
The rats had never been exposed to THC previously. They administered THC vapor to the rats in sealed environments. Afterwards, they used the brain implants to monitor the rats’ brain activity in several regions of the brain. Khokar states that the THC vapor caused a noticeable decline in brain activity across several regions of the brain that even hampered communication across the varied regions. According to the research, it’s the same effect that has been noted in human schizophrenia patients or those who suffer other forms of psychosis.
The diminished, psychosis-linked brain activity in the rats lasted up to a week after the THC exposure. It brings up concerns about cannabis users who have a genetic disposition for schizophrenia or other mental illnesses. Khokar points out that with the popularity of vaping THC rising with marijuana legalization and the health scares and deaths that have resulted from it, these results should raise concerns. Additionally, those who cultivate cannabis are creating more concentrated versions of the plant that make THC more potent. That can only serve to increase the intensity of psychotic episodes and Khokar believes further study is needed to find out more details about the causal link between THC and brain function.
21 And a mighty angel took up a stone like a great millstone, and cast it into the sea, saying, Thus with violence shall that great city Babylon be thrown down, and shall be found no more at all…
23 And the light of a candle shall shine no more at all in thee; and the voice of the bridegroom and of the bride shall be heard no more at all in thee: for thy merchants were the great men of the earth; for by thy sorceries [pharmakeia, drugs] were all nations deceived. Revelation 18
