After the 1912 Hague conference asked for study of Indian hemp, the colonial government tasked Willem G. Boorsma, head of the pharmacological laboratory, with examining cannabis in the Dutch East Indies.[1] His study found no significant problem — widespread consumption stayed limited to Aceh and East and West Sumatra, with small-scale personal cultivation mainly among Indian-mainland communities known as Klings — so no ban followed, though regional administrators had to report annually and plantation leases began forbidding psychoactive crops without authorisation.[1]
