The aviation ministry has asked the regulator to revise the existing testing framework, increase the proportion of personnel subjected to mandatory dope tests and impose tougher penalties on those who test positive for recreational or prohibited drugs. At the same time, officials have been asked to provide additional opportunities to personnel whose positive results are attributable to prescribed medicines.
