At least some of those benefits are thought to come from cannabidiol, a chemical component of the marijuana plant not thought to produce mind-altering effects. But there's a lot left to learn abo...
Indeed, a number of studies have found evidence of brain changes in teens and young adults who smoke marijuana. In 2013, Rocío Martín-Santos, MD, PhD, at the University of Barcelona, and colleagues reviewed 43 studies of chronic cannabis use and the brain. They found consistent evidence of both structural brain abnormalities and altered neural acti...
But the case against marijuana isn't closed. Other studies have failed to turn up evidence that marijuana use results in brain abnormalities. In one recent example, Barbara Weiland, PhD, at the University of Colorado at Boulder, and colleagues attempted to replicate Gilman's study in adolescents and adults who smoked marijuana daily. But Weiland's ...
Despite these questions, nearly half of U.S. states have already legalized marijuana in some form, and more are likely to follow suit. A number of researchers are now turning their attention to the question of how those laws might affect young people. Esther K. Choo, MD, MPH, of Brown University, and colleagues used data on more than 11 million hig...
Jun 1, 2023 · The latest findings are shedding light on how biological brain differences may influence cognitive effects in adolescent users, how cannabis can interfere with pharmaceutical medications for depression and other mental health issues, and the potential mental benefits for older adults.
Aug 1, 2020 · We review the changing epidemiology of cannabis use and provide an update on medical use, routes of administration, synthetic marijuana and other novel products, the effect of cannabis on the developing brain, other health and social consequences of use, and issues related to marijuana legalization.
Systematically review the scientific literature to characterize the effects of cannabis use on brain structure, function, and neurodevelopmental outcomes in adolescents and young adults with ADHD.
