Yaba pills are a mixture of methamphetamine and caffeine, and are popular in south-eastern Asia.

According to UNODC, the UN drugs agency, “Users get an intense ‘burst’ of energy, followed by increased activity, decreased appetite and a general sense of well-being.

According to the agency, the effects wear off, the user crashes and experiences prolonged periods of sleep and depression.

UNODC also warns that excessive doses can result in convulsion, seizure and death from respiratory failure, stroke or heart failure.
