A Church of Scientology group has been targeting Victorian schools with propaganda about the dangers of psychiatrists, antidepressants and ADHD medication.

It has prompted Education Minister James Merlino to urge principals to toss out the DVDs, letters and glossy pamphlets from the Scientology group.

"We trust that they are able to choose correctly what information is useful for their school and I am confident this would be thrown in the bin," he said.

Earlier this week, the Australian office of the Citizens Committee on Human Rights – which was established by the Church of Scientology – sent material about the "psychiatric drugging of Australian children" to every principal in the state.
