Police will keep powers to arrest cannabis users

Police will retain the power to arrest cannabis users to protect children, under reforms to be announced this week by David Blunkett.

The Home Secretary was consulting ministers this weekend on his final plans to reclassify cannabis from a class B to a class C drug, which will abolish police powers of arrest in most cases. The police warned that total abolition could lead to humiliation of the police by drug users.

Kate Hoey, a former minister, led Labour backbench criticism of the experiment in Brixton of a ''softly-softly'' approach to cannabis. Residents said it had made the streets more unsafe.

Mr Blunkett will announce that police will have the power to arrest cannabis users where they feel public order or the interests of children could be put at risk.

Whitehall sources said it would mean the police could arrest people flouting the law by openly smoking cannabis on the steps of a police station.

Mr Blunkett also will reject calls to lower the classification of ecstasy to a soft drug. He has also rejected a cross-party recommendation for ''shooting galleries'' to be provided for heroin addicts.
