the ethnic insurgent Shan State Armys of Burma.
Not unlike the development of opium-derivative Heroin in 1960s Yaba also was developed by CIA-controlled American scientists in late 1970s and widely distributed by Thai criminal networks under the protection of Laotian and Thai authorities.
Similar to the later development of Heroin the drug Yaba was eventually copied and manufactured by powerful ethnic insurgent armies in Burma and imported across the border back into Thailand.
In Thai Ya is medicine or pill and ba is mad or crazy, so Yaba in English simply is The Crazy Pill. Yaba is extremely popular in Thailand, where it is now imported from Burma or Laos even though it is sometimes manufactured locally in Thailand.
There are many different versions of Yaba and the most common are colored in red, orange, or lime green and carry logos such as "R" or "WY". They are small and round, roughly 6 mm in diameter, which means they can be packed inside a regular drinking straw for easy transportation or in a reusable 'mint' container.
In both Burma and Thailand Yaba pills are normally smoked "chasing" on aluminium foil or inside covers of cigarette packs: placing part of the pill on aluminium foil and inhaling the fumes through a straw as a lighter slowly heats the aluminium foil.
It is also common to simply swallow the drug in pill form; this method lengthens the duration of the drug to between eight and 16 hours, as compared to one to three hours when smoked, and reduces the intensity considerably. Strength and quality varies depending on the pill-source and the active ingredients are caffeine and methamphetamine.
Methamphetamine has a high potential for abuse and addiction, activating the psychological reward system by triggering a cascading release of dopamine in the brain characterized as Amphetamine/Stimulant psychosis.
The peak of the drug's effects is followed by a come down period lasting 6–10 hours, during which the user may have difficulty sleeping or eating. Many users report that it takes them up to 24-hours after consumption to be able to fall asleep.
In 2010 alone, Burma was estimated to have trafficked one billion Yaba tablets to neighboring Thailand. Ethnic militias and rebel groups (in particular the Shan State Armys – SSA-- and the United Wa State Army -- UWSA) are responsible for much of this production; however, the Burmese military units are believed to be heavily involved in the trafficking of the Yaba pills.
