Duncan Duffy pleaded guilty to driving while unfit through drugs and possession of cannabis.

Kirklees magistrates were told that police stopped him as he drove along Lower Fitzwilliam Street near Huddersfield town centre on January 19.

They could smell cannabis on him and arrested him after he provided a positive swab test at the roadside, prosecutor Vanessa Jones said.

A police station blood test revealed that the 37-year-old had no less than 7.6 microgrammes of the drug per litre of blood.

This was almost four times over the legal limit of two microgrammes.

Duffy, of May Street in Crosland Moor received a police caution for possession of cannabis in 2009.
