Although until now the legalization of this plant is still controversial, in fact since 3,000 BC some medical literature from China, India, Greece, and Arabia have recorded marijuana as an effective pain cream. Some of the benefits are as a pain reliever, improve memory, overcome digestive disorders, or respiratory inflammation. The medical records of the Arabs in the 11th century also mentioned that the juice from cannabis leaves could cure abscesses in the head. A century later, Ibn-al-Baytar proved the efficacy of oil from cannabis seeds to remove tumors that had hardened. Even marijuana seeds have been recorded for the treatment of uterine tumors. Thanks to its efficacy as a medicine, this plant spreads rapidly to Europe, America, Arabia, and Asia. However, the negative impact due to abuse also cannot be considered trivial. Usage doses that are too high have the potential to damage the nerves, make a person feel excessive euphoria, interfere with mental health, and cause addiction. Therefore, now the use of marijuana is widely prohibited by the government.

According to Mahmoud ElSohly, Ph.D., Cannabis plant researcher, there are around 500 chemicals in marijuana. The main active substances are tetrahydrocannabinol (THC) and cannabidiol (CBD). If formulated with the right dose, THC or substances that can make this fly can be a panacea. Whereas CBD is a substance that binds to receptors in the body and affects the immune system and brain. Misuse of use such as marijuana, which is burned at high temperatures, makes 500 chemicals in marijuana to have side effects as a trigger for cancer if sucked into the body. Therefore, to get a positive effect, cannabis use cannot be arbitrary. Its use must be under the supervision of a doctor and not excessive. Promotion of research led by knowledge is indispensable because this is where all things related to application development. Although there is a long way from mice to humans, he feels very positive about the prospect that THC can be used to treat dementia.
