Of the 135 people who gave urine samples for the “purple pee” test, 20 tested positive – equivalent to just under 15 per cent.
Of these, 17 were sent to a “behaviour adjustment” camp conducted by Srisoonthorn Health Office, while the other three, all underage and students (one from Kathu Wittaya School and two from Phuket Technical College) were collected by parents and school heads of discipline.
