The endocannabinoid system is one of the few pathways in the nervous system which send messages backwards. This uncommon occurrence always for the endogenous cannabinoids to regulate messages sent through the nervous system. This is important because if there is an overproduction of neurotransmitters the endocannabinoid system kicks in to suppress the overproduction of the neurotransmitters. Over productions of neurotransmitters cause a number of conditions like Parkinson. Such conditions involve uncontrollable shaking and motor lose. Studies show that these symptoms can be suppressed by the addition of cannabinoids. One of the most successful, but controversial methods of getting these compounds is by the use of medical marijuana. Although studies have shown marijuana has medical applications it is still classified as a schedule one controlled substance. With this classification it is illegal to carry it over state lines and has no medical benefits. These laws remain in place due to social stigmatisms and political/economic blockades. This doesn’t mean debate isn’t needed on the subject but the facts cannot be continuously over looked just because stigmas and blockades of the past continue to surface. For or against the subject, ignoring the facts would be a mistake, one in which could change people’s lives.
