Why to Blood Test Drugs and Alcohol in Your System

If you have been drinking, understanding and being aware of how long alcohol can remain in your system is crucial information for avoiding dangerous interactions involving medications and impairments in your physical and mental capabilities. Most companies and businesses have developed and implemented drug and alcohol testing policies in the workplace to deter and detect the use of illicit drugs, alcohol, or prescription drugs. These policies may include conducting a blood test for drugs and alcohol. 

Blood Test Drugs and Alcohol

To blood test drugs and alcohol is considered a more invasive drug and alcohol testing method than conducting breath tests and urine tests. However, blood testing is the most effective method of detecting specific alcohol concentration levels in your system. Running a blood test for drugs and alcohol will show precise levels of intoxication 24 hours after drinking. Due to the invasive nature of blood testing that would require a needle in the arm, there are labs and other drug and alcohol testing facilities offering an option for less invasive blood testing methods. Blood tests results can give better details than conducting urine tests and reveal more information other than just the presence of drugs in your system.  

Workplace drug and alcohol testing 

If you consider implementing a workplace drug and alcohol policy, you should determine why you need to have that policy in place? What kind of issues are you trying to manage? Will you be conducting a blood test for drug and alcohol detection? 

Workplace safety – Substance abuse can cause an increase in workplace accidents. Industries like mining, transportation, and aviation where a drug or alcohol-impaired employee can be considered a safety hazard must have drug and alcohol policies in place. 

Employee performance – Illicit drug use and alcohol consumption can have an adverse impact on an employee’s ability to do their job correctly. Alcohol and drug use also contributes to an increase in employee lateness and absenteeism.  

Legal Liability – As an employer, you must provide your employees with a safe working environment and maintain that safety. Employees impaired by drugs or alcohol should not be allowed as they may risk causing workplace accidents. 

Drug and Alcohol Standards 

Your company workplace policy should comply with the Australian Standards.  

  • Urine Testing – AS/NZS 4308:2008 
  • Saliva Testing – AS 4760:2006 
  • Alcohol Testing – AS 3547:1997 

Suppose an employee violates your drug or alcohol policy, either by refusing to get tested or by testing positive. In that case, you may be able to dismiss them for failing to follow a lawful and reasonable direction.
