Manx MHK Bill Mallarkey said the comments were "irresponsible".
I'd be surprised if Mick Jagger could remember where the Isle of Man is

"The whole question of legalising drugs is fraught. You usually try these things out in very small places. You know, like you try a new product out in a small kind of society or an island somewhere.
"In England they always try out new mobile phones in the Isle of Man. They've got a captive society. You should try the legalisation of all drugs on the Isle of Man and see what happens."Bill Mallarkey, MHK with responsibility for the Manx drug and alcohol strategy, said:
"Jagger's comments are out of order and irresponsible to suggest that people on the Isle of Man should be used as social guinea pigs. I'd be surprised if Mick Jagger could remember where the Isle of Man is, as he's not been here since a concert in 1964 to my knowledge.
"If he does want to come and discuss this any further he'd better not bring any drugs with him as the Isle of Man has a zero tolerance policy on possession of drugs and severe penalties for drug-dealing."Under Manx law, drug dealers of class A or B drugs can be imprisoned for up to 14 years.
