Medical marijuana may have positive medical benefits, but there are also well-documented negative effects. Some negative effects to the central nervous system include changes in sensory perception, altered thought formation and expression, short-term memory problems, and impaired thinking and learning. Negative physical effects include impaired motor performance, loss of balance and coordination, decreased attentiveness and alertness, prolonged response time to stimuli and danger, decreased ability to judge distance and space, and impaired ability to perform complex tasks.
