Since 1970, David Watson has traveled extensively to cannabis producing countries looking for seeds of unusual varieties, and in 1975 established Sacred Seeds, the world’s first cannabis seed company, in California. In 1986, he began Cultivator’s Choice, Amsterdam’s first cannabis seed company, breeding and introducing many foundation sinsemilla varieties still grown today. In 1992, Mr. Watson established HortaPharm BV, the world’s first established medical cannabis corporation and in 1993 he co-founded the International Hemp Association. Working under license from the Dutch Ministry of Health, HortaPharm established facilities used to breed medical cultivars and conduct cannabis research and development. Mr. Watson formulated HortaPharm’s research goals and created the team led by Dr. Etienne De Meijer that was the first to use STS as a breeding method to “self” cannabis plants and create single cannabinoid cultivars. In 1998, HortaPharm supplied varieties along with organic cultivation and integrated pest management expertise to GW Pharmaceuticals in the United Kingdom and assisted in selecting the cultivars used to produce Sativex® and other GW varieties. Mr. Watson co-authored Hemp Diseases and Pests (2000) with John McPartland and Robert Clarke, contributed to Franjo Grotenhermen’s Cannabis and Cannabinoids and Mahmoud ElSohly’s Marijuana and Cannabinoids, as well as many other articles.
