Weed of flowers, leaves and ears of cannabis hemp are smoked in the form of a cigarette to get a psychotropic effect. Because of this psychological effect, it is used for amusement (pleasure) and becomes a problem. Originally used as a religious ceremony in ancient times, this ingredient has fallen into a tool of pleasure to enjoy the reaction of the body not only to the brain but also to the body as it reacts variously, and these ingredients are addictive, causing people to go to the path of suffering. The ingredients in cannabis are not necessarily bad here. Just as Dokdo is good medicine, Hyundai is used in various medical fields. From this point of view, hemp itself seems to be a human problem of how hemp is used as a problem.
