Stoned young rats fail memory tests

‘Researchers at the University of Sydney have found that adolescent rats are more vulnerable to adverse effects of cannabis than adult rats.

Professor Ian McGregor says rats’ brains basically respond to drugs the same way as humans but they are easier to work with because they are not polydrug users.

He says his team gave the rats cannabis then took them off the drug for two weeks before testing their long-term memory.

“We found that the adolescents that had been given cannabis had impaired memory, relative to adolescent rats that hadn’t had cannabis exposure,” he said.

“Then when we compared them to adults we found there was very little memory deficits in the adults rats that had been given cannabis.”‘
