Arrests for heroin and crack cocaine in Weston have dropped significantly over the last five years - but for cannabis possession, the number's almost doubled.

Heroin offences now make up just nine percent of drugs arrests in the town, down from twenty in 2006 - while for cocaine the figure's at just sixty percent of the level it was in 2008.

But the number of those caught with Class B cannabis has gone up ninety-one percent.

Police reckon it's due to a combination of rising prices of Class A drugs, and a crackdown on cannabis dealers.
