Dr. Mahlberg obtained one of only two Drug Enforcement Administration (DEA) Schedule 1 research licenses to pursue studies on Cannabis in the United States spanning a period of 33 years from 1970-2003. During that time he accumulated one of the most extensive seed banks in the world with over 200 strains (varieties) of Cannabis from worldwide sources including landrace varieties, which were cultivated in secure greenhouses. The studies are available in over 30 scientific publications on Cannabis.
