Smoking pot may impair your coordination and other motor skills, a new review of studies finds. In the review, researchers found that people who used marijuana had differences in brain areas called the corticostriatal networks compared with people who didn't use the drug. These areas are connected to motor learning and control, and can affect people's reaction time, memory, and the ability to switch between tasks, according to studies included in the review.
According to other studies a certain percentage of people (like me) suffer anxiety attacks when high on weed.
All in all this isn't enough to keep it illegal as a class 1 'bad' drug, but there is enough evidence that we shouldn't make it totally legal either.
Put it out there somewhere in limbo!
