A disabled pro-cannabis campaigner has been jailed for six months after opening a Dutch-style coffee shop.

Protesters wept and shouted: "You're sending a cripple to jail" when Chris Baldwin, 53, of Carnegie Close, Worthing, was imprisoned for his involvement in the notorious Quantum Leaf caf in Rowlands Road, Worthing.

Police had to clear Chichester Crown Court when some of the 30-strong group refused to leave the public gallery.

During a series of police raids in November 2002, officers stormed the caf, set in a back room of smoking accessory shop Bongchuffa. Officers found an estimated £2,000 worth of cannabis plus more than £4,000 in cash.

At yesterday's hearing, Judge John Sessions accepted Baldwin had opened the caf as a political statement to encourage the Government to legalise the soon-to-be reclassified class B drug and to provide free cannabis for people with painful health conditions.

Peter Woodall, in mitigation, said further cannabis possession offences were due to Baldwin suffering from spastic paraplegia since the age of seven.

The campaigner, who stood for the Legalise Cannabis Alliance (LCA) in the 1997 General Election, used marijuana to alleviate his consequent leg spasms.

Former Metropolitan police Detective Chief Superintendent Edward Ellison, who served in the drugs squad for seven years and had met Baldwin at LCA marches, spoke as a character witness.

However, the judge said ignoring Baldwin's two previous suspended prison sentences for other drug offences would make "a mockery of the law".

He said: "With considerable reluctance, I have no alternative to a custodial sentence, which I have reduced to take into account the impending reclassification of sentencing."

Baldwin had pleaded guilty to allowing cannabis to be used at a property, possession with intent to supply cannabis and possession of cannabis.

Before the hearing, he said: "I'd written hundreds of letters to the Home Office, went to every pro-cannabis rally, march and meeting and lobbied Parliament. I felt a coffee shop was at the sharp end of the political campaign."

Mark Benson, 37, of Irene Avenue, Lancing, who worked in the Bongchuffa shop, pleaded guilty to permitting cannabis to be used in a premises and cultivating cannabis plants. He was given a four-month curfew order.

Winston Matthews, 47, of Court Lodge Road, Horley, was given a suspended four-month jail term after he admitted possession of cannabis with intent to supply, supplying cannabis, possession and cultivation of cannabis.
