Dope isn't to blame for hazy memories

Middle-aged adults whose memories have grown hazy can't blame occasional pot smoking drug use for their forgetfulness, a new study shows.

However experts still warn that heavy, prolonged use could harm mental functions.

The study, carried in the American Journal of Epidemiology, tested the mental function and memory of nearly 9,000 Britons at age 50 and found that those who had used illegal drugs as recently as in their 40s did just as well, or slightly better, than peers who had never used drugs.

"Overall, at the population level, the results seem to suggest that past or even current illicit drug use is not necessarily associated with impaired cognitive functioning in early middle age," said lead researcher Alex Dregan.

"However, our results do not exclude possible harmful effects in some individuals who may be heavily exposed to drugs over longer periods of time."
