"Research suggests even experimenting [with marijuana] can cause brain damage."

In a report on people growing marijuana for BBC Radio 4’s Today programme on Thursday, 24th April 2014, journalist Sima Kotecha said that “Harvard University research suggests even experimenting can cause brain damage”. She was referring to a paper published in the Journal of Neuroscience last week which did not show brain damage.

We asked Professor David Nutt, Chair of the Independent Scientific Committee on Drugs to respond:

“A change in brain structure by itself doesn't necessarily mean damage. It could mean improvement in efficiency or just a different way of working.”

Lion Patcher, professor of computational biology at University of California Berkley, explains a number problems with the study itself.
