How Cannabinol Is Utilized in Japan, a Country with Strict Cannabis Regulations—Its Purposes, Medical Effects, Adverse Events, and Dependence

Introduction: Cannabinol (CBN) was discovered in 1896, but its commercial use did not take off until recently, and there have been few studies on its use, safety, and efficacy. Japan has strict regulations on cannabis, but CBN products have been legally distributed since late 2020. It is possible to speculate that these products are used for different purposes than in places such as some states of the United States where cannabis is legal, but no academic research has been conducted to date.
