Police will be able to use "drugalysers" to screen for cannabis and cocaine at the roadside.
Officers will also be able to test for these and other drugs including ecstasy, LSD, ketamine and heroin at a police station, even if a driver passes the roadside check.
They need to blood test for lsd. Saliva testing is not possible for lsd. The active dose is too low and the half life too short for saliva to be a successful roadside test substrate. If you look like you are tripping balls they have the powers to detain you and conduct further tests back at the station of hospital. You'd be extremly unlucky to test for lsd the next day.
