“Cannabis is a historical plant which has been used as a medicine in East Asia.

Cannabis was prescribed in Meiji era of Japan to alleviate pain and cure the digestive, respiratory, urinary, and nervous system diseases such as indigestion, asthma, tuberculosis, gonorrhea and its complications, insomnia, and nervous prostration.

Cannabis was medically used in Meiji era of Japan and the reporting and sharing of its clinical effect was published on the medical journals like present days.

There were already Cannabis regulations in that era, but its medicinal use was more liberated than nowadays.

It may be a chance to reconsider the current legal system, which strictly controls the use of Cannabis.”
