新研究将经常使用大麻与年轻成年人工作记忆功能下降14%联系起来。 New study links frequent marijuana use to a 14% drop in working memory function in young adults.

JAMA网络Open的一项主要研究发现,经常使用大麻会损害年轻成年人的工作记忆。 A major study in JAMA Network Open finds that frequent marijuana use can harm working memory in young adults. 研究人员分析了1 000多名22至36岁的参与者,发现重型用户在记忆任务期间的脑活动减少了14%,影响到决策、记忆、注意力和情感处理等领域。 Researchers analyzed over 1,000 participants aged 22 to 36 and found that heavy users displayed a 14% reduction in brain activity during memory tasks, affecting areas responsible for decision-making, memory, attention, and emotional processing. 慢性使用似乎比最近使用的影响更大,尽管研究无法确定退出后记忆是否得到改善。 Chronic use appeared more impactful than recent use, though the study could not determine if memory improves after quitting.
