// Definition
An organization co-founded by David Watson and Robert Connell Clark in the early 1990s in Amsterdam that served as the first dedicated scientific information clearinghouse for hemp research, publishing peer-reviewed articles and connecting researchers worldwide during a period when hemp science had virtually no outlet.
// From the Episode
Rob Clark describes the IHA as David Watson's idea, launching its first journal issue around 1993-94. It focused on the non-medical aspects of the cannabis plant, publishing research from Ukrainian and other international scientists who had no English-language outlet. Fletch credits the IHA with enabling hemp growing in Manitoba, Canada through its professional documentation. The organization connected breeders with heritage hemp seed collections.
