Myanmar is one of the main destinations for trafficked preparations containing ephedrine and pseudoephedrine, and precursor chemicals seized in Myanmar mainly originated in nearby countries, primarily China, India and, to a lesser degree, Thailand. To circumvent national legislative controls on precursor chemicals, more non-scheduled precursor chemicals and/or pre-precursors are being used. In 2014, more than half of the crystalline methamphetamine in the country was synthesized using 2-bromopropiophenone.
