Abstract : In recent years, there has been an increasing interest in the use of medical cannabis and its importance in medical treatment. Particularly, this issue of using medical cannabis has received considerable critical attention in epilepsy disorder and chronic non-cancer pain. The purpose of this paper is to review recent research to determine the effect of medical cannabis as a form of medication. It suggests that there is a positive relationship between the use of medical cannabis and the reduction in the number of seizure frequency for those who suffer from epilepsy diseases. The paper also discusses the other argument evidencing that medical cannabis has a negative effect on those with chronic non-cancer pain. Finally, it concludes that medical cannabis is useful for the treatment of epilepsy diseases. At the same time, there should also be continued efforts to make the decision about using medical cannabis more accessible for medical purposes. A major recommendation in this paper is to continue conducting further research and to have support from the government in order to consolidate this finding.
