Regular cannabis use has significant effects on the shape, size and performance of the brain
A new study has found that someone who uses marijuana regularly has, on average, less gray matter the front brain, compared to people who do not smoke marijuana.
The front part of the brain is called the orbital frontal cortex. This region of the brain plays a key role in the brain's reward, motivation, decision-making and addictive behaviors network. The frontal brain is vital to the cognitive processes of decision-making. This brain shrinkage appears to lessen motivation and decision making capabilities.
Questions surrounding the effects of chronic marijuana use on brain structure continue to increase!
Ben Cort, director of the Center for Dependency, Addiction & Rehabilitation at the University of Colorado Hospital, has stated that the study showed once again that pot is "not a benign substance."
The lead author of the study, published by the National Academy of Sciences, is Francesca Filbey, Associate Professor, University of Texas Center for Brain Health. See Long-term effects of marijuana use on the brain.
