Are legal drugs cheap in Thailand?
They are often reasonable than in the west, though not always. Generic malarias for example are a fraction of the cost of a similar product in the west, while migraine medication is a very similar cost. Insulin is very expensive in Thailand when compared to the west. However, some types of drugs are Thai made, some are imported by neighbor countries and some are imported from west countries. So the price differs according to the origin of the drugs.
