Below are some of the more serious drug cases to have passed through Sheffield Crown Court and other courts recently involving a variety of illegal substances.
Offenders have been involved in dealing class A drugs including heroin and crack cocaine and two others were involved in smuggling drugs into a prison.
One dealer was brought to justice after road traffic police stopped his vehicle because of a broken brake light, while another offender was jailed for producing cannabis after 331 plants were found at a Sheffield property.
But judges have seen fit to punish these offenders appropriately with custodial sentences of varying lengths.
