Under the [[Police and Criminal Evidence Act 1984]](PACE), it had been possible for police to drug test Detained Prisoners since 1984. The Drugs Act 2005 introduced, at selected "intensive DIP area" police stations, a mandatory drug test for every individual who had been arrested for a specified list of "trigger offences."; Trigger offences whichwere hadfirst beenset shownout toin the Criminal Justice and Court Services Act 2000, and constitute a list of offences known have a clear link to substance misuse, (such as [[Theft]]). Arrestees may also be tested for 'non-trigger' offences (including, for example, those related to prostitution) with the authority of a police inspector. Individuals who refused to take this test, a "non-intimate saliva sample", could face up to three months in [[police custody|custody]] and a £2,500 [[Fine (penalty)|fine]]. Individuals who tested positive were then compelled to undergo a two-part "Required Assessment" with a drug worker from their local DIP.
