The "war on drugs" was largely won in Asian countries that have proper enforcement (Japan, Singapore, Taiwan, etc...) Just compare the streets of Tokyo to that

The "war on drugs" was largely won in Asian countries that have proper enforcement (Japan, Singapore, Taiwan, etc...) Just compare the streets of Tokyo to that of San Francisco and tell me it is not working! Also, compare driver (and pedestrian) behaviour in Japan. In urban areas, both largely follows the rules and it is safer. (Strict liability for drivers may also be a part of it...)
