Dutch ban on "magic" mushrooms to take effect

By Catherine Hornby

AMSTERDAM (Reuters) - The Netherlands will ban the sale and cultivation of all hallucinogenic "magic" mushrooms from next week, the latest target of a country seeking to shed its "anything goes" image.

The Dutch government proposed the ban in April, citing the dangerous behavioural effects of magic mushrooms following the death of a French teenager who jumped from an Amsterdam bridge in 2007 after consuming the hallucinogenic fungus.

"The use of magic mushrooms has hallucinogenic effects. It is proven that this can lead to unpredictable and therefore risky behaviour," the Dutch Health Ministry said in a statement.

A challenge to the ban was rejected by a court in the Hague on Friday. From December 1 the production or sale of fresh magic mushrooms could lead to a maximum jail sentence of four years, a spokesman for the Dutch Justice Ministry said on Friday.

"We are targeting the growers and the shops who are selling the mushrooms," the spokesman said.

The active ingredient in magic mushrooms is psilocybin. Effects last up to about six hours and can include nausea, vomiting, muscle weakness and drowsiness in the early stages after consumption.

The psychological consequences of psilocybin use include hallucinations and an inability to discern fantasy from reality. Panic reactions and psychosis also may occur, particularly if a user ingests a large dose, according to the U.S. Justice Dept's National Drug Intelligence Centre.

Some proponents of magic mushrooms say that their use aids in spiritual awareness, gaining personal insight and meditation.
