Yaba (drug)

Yaba (ยาบ้า; also Ya Ba, Yaa baa, Yabba, Ya baa or Yah Bah; "crazy medicine" in Thai) are tablets containing a mixture of methamphetamine and caffeine, typically brightly colored in orange or green and carrying logos such as "R" or "WY". Quality varies according to source, most are manufactured for oral administration or 'chasing' on foil; there is a brand preferred for injecting from Laos. This illegal drug is especially popular in Thailand, where it is imported from neighboring Burma. In recent years it has also been used by immigrant populations in the United States, and occasionally as a club drug replacing ecstasy.
