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 ...
A large study from the University of Colorado found heavy cannabis use is linked to reduced brain activity. Lead researcher Joshua Gowin and neurosurgeon Paul Saphier discuss the impact on health.
Approximately one-third of individuals with acute necrotizing encephalopathy type 1 do not survive their illness and subsequent neurological decline. Of those who do survive, about half have permanent brain damage due to tissue necrosis, resulting in impairments in walking, speech, and other basic functions, there may also be permanent brain ...
In what researchers are calling the largest dataset used to study cannabis and brain function, over 1,000 former or current cannabis users underwent brain scans while completing seven different ...
Researchers examined data on over 1,000 former or current cannabis users — roughly half males and half females ages 22 to 36 years — who underwent functional MRI brain scans while completing ...
A dried cannabis flower. The short-term effects of cannabis are caused by many chemical compounds in the cannabis plant, including 113 [clarification needed] different cannabinoids, such as tetrahydrocannabinol, and 120 terpenes, [1] which allow its drug to have various psychological and physiological effects on the human body.
Researchers found that 63% of lifetime heavy cannabis-using participants and 68% of recent cannabis users showed reduced brain activity during their working memory task.
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 ...
