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 observed effects on memory and learning, they said, showed long-term cannabis use caused "selective memory defects", but "of a very small magnitude". [85] A study by Johns Hopkins University School of Medicine found that heavy cannabis use is associated with decrements in neurocognitive performance even after 28 days of abstinence.
Acute cannabis intoxication has been shown to negatively affect attention, psychomotor task ability, and short-term memory. [14] [15] Studies of chronic cannabis users have demonstrated, although inconsistently, a long-lasting effect on the attention span, memory function, and cognitive abilities of moderate-dose, long-term users. Once cannabis ...
Cannabinoids (/ k ə ˈ n æ b ə n ɔɪ d z ˌ ˈ k æ n ə b ə n ɔɪ d z /) are several structural classes of compounds found in the cannabis plant primarily and most animal organisms (although insects lack such receptors) or as synthetic compounds.
Δ-8-tetrahydrocannabinol (delta-8-THC, [a] Δ 8-THC) is a psychoactive cannabinoid found in the cannabis plant. [1] It is an isomer of delta-9-tetrahydrocannabinol (delta-9-THC, Δ 9-THC), the compound commonly known as THC, with which it co-occurs in hemp; natural quantities of ∆ 8-THC found in hemp are low.
The book's chapters thus address issues of marijuana's real or putative effects on sex hormones and reproduction, lungs, the immune system, the brain, memory, cognition and motivation; the gateway theory and addiction; crime, deviance and punishment, and so on -- in other words, virtually all the concerns that have been raised for decades in ...
The presence of these specialized cannabinoid receptors in the brain led researchers to the discovery of endocannabinoids, such as anandamide and 2-arachidonoyl glyceride . [ citation needed ] THC is a lipophilic molecule [ 27 ] and may bind non-specifically to a variety of entities in the brain and body, such as adipose tissue (fat).
