Although Indonesia had achieved self-sufficiency in basic pharmaceutical production by the early 1990s, Indonesians had the lowest per capita expenditure for Western-style drugs in ASEAN. Most people appeared to rely at least partially on traditional herbal medicines, in part because the Western-style drugs were expensive. Quality control for the country's pharmacies was lax, but efforts were being made in 1992 to improve enforcement of new laws designed to control drug quality. By the late 1980s, Indonesia had more than 300 pharmaceutical companies and nearly 1,000 pharmaceutical wholesalers. Most were located in Java.
