Heavy Use of Marijuana May Cause Brain Damage

أساسيات تداول الخيارات الثنائية marijuanaThe heavy, daily use of marijuana for an extended period of time can detrimentally change brain structures and cause memory impairments.[1] In fact, researchers found that teens who were heavy marijuana users—smoking daily for approximately three years—had abnormal changes in their brain structures that were related to working memory.1 They performed poorly on memory tasks, which leads to poor academic performance and everyday functioning.1
