Assistant Deputy for Development of State Apparatus Discipline and Integrity Bambang Dayanto Sumarsono said civil servants may still keep their job if found using drug only once and was punished by the law only for less than two year jail term.
"But no more tolerance for those found using drug twice or selling drug," Bambang said here on Monday.
He said drug users are generally sent to the rehabilitation centers, but some had stood trial and were sentenced.
He said as for disciplinary sanction is the responsibility of the Civil Servant Development Authority (PPK).
The government has stepped up the campaign against drug abuses and trafficking in the country.
The government has declared the country is in emergency of drug crisis.
