The study, published in the journal JAMA Open Network, is the "largest of its kind," according to the university, using brain imaging technology to examine the effects of cannabis use on 1,000 ...
A 2012 review of cannabis use and dependency in the United States by Danovitch et al said that "42% of persons over age 12 have used cannabis at least once in their lifetime, 11.5% have used within the past year, and 1.8% have met diagnostic criteria for cannabis abuse or dependence within the past year. Among individuals who have ever used ...
New research shows that heavy lifetime use of cannabis — more than 1,000 times — is associated with reduced activity in areas of the brain involved in working memory. The study adds to ...
Researchers found 63% of heavy lifetime cannabis users exhibited reduced brain activity during a working memory task, while 68% of people who tested positive for recent use of cannabis also ...
Legal cannabis (marijuana) product. Overconsumption and reliance could lead to cannabis-induced amotivational syndrome. The term amotivational syndrome was first devised to understand and explain the diminished drive and desire to work or compete among the population of youth who are frequent consumers of cannabis and has since been researched through various methodological studies with this ...
The research team, headed by Igor Grant, found that cannabis use affects perception but does not cause permanent brain damage. Researchers looked at data from 15 previously published controlled studies involving 704 long-term cannabis users and 484 nonusers.

Unlike alcohol, which is water soluble and evenly distributed through your blood, THC is fat soluble, which means it’s harder to test for in blood or breath. With edibles, THC concentrations in ...
The brain is more vulnerable to oxidative stress than other organs, due to its low oxidative capacity. Because neurons are characterized as postmitotic cells, meaning that they live with accumulated damage over the years, accumulation of ROS is fatal. Thus, increased levels of ROS age neurons, which leads to accelerated neurodegenerative ...
