The effects of cannabinoids have been tested and have found to be diverse, for example when cannabinoids are administered can have a bronchodilator effect. when cannabinoids are administered. Throughout the circulatory system, tachycardia and increased cardiac output can occur, which can cause a drop in blood pressure, cannabinoids have been known to decrease these negative effects, although it can be a hypotensive substance. For our eyes, we have discovered that cannabinoids are important for the treatment of glaucoma because they decrease the tension in the eyeball. In the digestive system we have found an inhibition of intestinal mobility, inhibition of gastric emptying and also a reduction in the secretion of gastric juice when cannabinoids are administered. In the central nervous system, ut is important to note that cannabinoids are inhibitors of neuronal hyper excitability, and manage the important areas such as memory and learning, in addition to regulating other vital functions. Cannabinoids work well on the endocrine system, they are good at reducing insulin resistance and increasing the utilization of glucose in patients with type II diabetes. Cannabinoids also exert multiple functions in other organs and systems of the body. As we already know, cannabinoids are useful for treating pain and to increase appetite in patients who have experienced weight loss, loss due to illnesses or some medicines; they are used to treat illnesses such as spasticity that exhibit these types of symptoms and to treat nausea and vomiting that occur from secondary treatments such as chemotherapy. Cannabinoids may also be successful in helping neurodegenerative diseases such as Alzheimer’s, Parkinson’s disease, Huntington’s disease, and demyelinating diseases such as amyotrophic lateral sclerosis or multiple sclerosis. Cannabinoids can cause antitumor effects in different types of cancer as well as anticonvulsant properties and anti-epileptic effects. Cannabinoids are useful for treating hyperkeratotic skin diseases such as psoriasis and eczema. They are also useful to treat inflammatory diseases inside the gut where we can find pathologies such as Crohn’s disease, ulcerative colitis and irritable colon. There are multiple studies being carried out on the effects of cannabinoids that are effective in treating other pathologies that indicate that they are effective. The endocannabinoid system is the most complex system that mammals and other species possess. We now know how to act, we know how the receptors are distrusted throughout the body, we are able to use phytocannabinoids through the endocannabinoid system to improve a variety of illnesses. The endocannabinoid system is a very complex structure; we are aware of the distribution of the receptors, the molecular mechanisms and we think that many diseases or pathologies occur as a result of a malfunction of our endocannabinoid system. Therefore, it is clear that we must continue studying phytocannabinoids in order to apply them to pathologies that are currently under study.
