Effects of chronic marijuana use include lung cancer, memory impairment, decreased blood flow to the brain, and reduced oxygen availability in all regions of the body.
Research has shown that people that use marijuana are more prone to suffer from lung cancer since the smoke of that drug has many of the harmful substances that tobacco has. Furthermore, chronic marijuana use can have neurobehavioral consequences such as memory impairment and decreased blood flow to the brain. Moreover, other negative side effects of marijuana are loss of sense of personal identity, sexual problems and lowered reaction time.
