Hungary's governing Fidesz party says it supports a proposal to administer yearly mandatory drug tests to children aged between 12 and 18.
Antal Rogan, head of the Fidesz parliamentary group, said the plan needs some "strong adjustments" but would protect children and fight drug trafficking and organised crime.
A draft of the Bill is expected to be ready in February for debate in parliament, where Fidesz has a two-thirds majority of seats.
Mr Rogan said the test results would be revealed only to parents and a positive test would have no legal consequences for minors.
Fidesz communications director Mate Kocsis said last week the tests would also apply to politicians and journalists. But Mr Rogan now says legal consultations are needed to see if those groups can be included.
