What drugs are tested for in a pre employment drug test ?
Pre employment drug and alcohol screening is now a common part of many evaluation tests, particularly for key employment roles in transport, construction and a growing number of support services and contract staff.
Employers are seeking to reduce their liability to accident and HSE risk. Drugs and alcohol are seen as an identifiable risk factor, and screening tests have never been cheaper, more reliable or easy to perform.
An increasing number of drug tests are now done using saliva tests. This is easy, direct and need no special environment to facilitate collection, making them convenient for employers to conduct even where a full medical is not being conducted.
Most drug screens will include a test for the 5 key or base line drugs. These are Cannabis, Cocaine, Amphetamine, Opiates (heroin) and Methamphetamine. Added to this base will be Benzodiazepines and possibly Methadone, depending on demographics and local problem drugs.
The combination of Amphetamine and methamphetamine ensures that most “party pills” will be detected as most will contain traces of one or the other.
Increasingly employers are looking to add Ketamine and other synthetic and legal highs to the drug screen, drug tests are now available for K2 synthetic cannabis, and Mephadrone (M Cat)
Urine drug testing will detect most substances for at least 3-5 days after use. Moving to a saliva screen reduces this to between 12 hours and 3 days.
