You all have heard that cannabis is used as a psychotropic drug. But cannabis has therapeutic properties, less widely publicized. When you hear about marijuana, few of you think that this plant has enough properties to make “good” and that could be successfully used in medical therapy of certain diseases.
Drug (THC), obtained from the leaves and flowers of cannabis, is a psychotropic substance that crosses the blood-brain barrier and directly affects the central nervous system (brain). Cannabis has the effect of altered perception, impaired consciousness, abnormal behavior and can induce varied moods: euphoria, overstimulation, hallucinations. Cannabis produces psychological and physical dependence.
Cannabis is used for millennia as a medicinal plant in China. Cannabis extracts (cannabinoid) obtained naturally or by chemical synthesis have the following properties: combat nausea and vomiting (useful when cancer patients following chemotherapy), stimulates the hunger centers in the hypothalamus (could have utility when patients following chemotherapy, or in the case of AIDS), analgesic (pain relief) by blocking nerve transmission of pain in the spinal nerves, decreases fertility in men by reducing the synthesis of ATP (energy reservoir) on the sperm, decreases pain and spasticity in multiple sclerosis.
Studies on laboratory animals have shown effectiveness of cannabinoid in the treatment of cancer or against neuronal degradation in Alzheimer’s disease or Parkinson (cannabinoid receptor stimulation has neuroprotective effects).
