'Surprising' vaping THC study in Ontario shows similarities to schizophrenia
A new study by Ontario researchers suggests that brain activity in rats exposed to the vapourized psychoactive component of marijuana is similar to those with schizophrenia and cannabis-induced psychosis.
Jibran Khokhar, an assistant professor of neuroscience at the University of Guelph, says the rodents' dampened brain activity lasted at least a week after exposure to T-H-C.
He says the fact the effects lasted that long was really surprising.
Khokhar and his team are now trying to tease out the long-known relationship between marijuana use and schizophrenia.
His team surgically implanted electrodes into the brains of eight healthy rats that had never been exposed to T-H-C.
After the animals recovered from the surgery, his team pumped pure vapourized THC or a saline solution into sealed rat chambers and monitored the animals' brain activity.
