MA is sometimes distributed in the form of tablets, often a combination of MA and caffeine or MA and MDMA. Tablets referred to as “Yaba” (which means “crazy medicine” in Thai) are typically produced in Southeast and East Asia. They are usually no larger than a pencil eraser, and are brightly colored, including reddish-orange or green. The tablets sometimes have a logo; for example, R or WY. In the United States, these tablets tend to be used by Asian communities, though they are also sometimes available at raves and techno-parties. Ecstasy tablets imported into the United States from Canada sometimes contain methamphetamine as well.
