Drug testing kits used for workplace drug testing generally test for the six most commonly used illegal drugs including amphetamines, methamphetamines, cocaine, opiates, marijuana, and benzodiazepines.
Drugs can affect us in different ways, and it varies from person to person. How a drug affects a person can depend on their weight, size, and health, their frequency in using their drug, and also the presence of any other drugs in their system. The effects are also dependent on the amount of drugs taken.
With illegal drugs, it can be hard to judge how much has been taken because they are uncontrolled, and therefore the quality and strength of the drug varies from batch to batch.
The effects of drugs, and the symptoms of coming down and withdrawal, can affect a person’s ability to work safely and effectively, which is why many organisations have a strict zero tolerance towards drugs and alcohol in the workplace.
