Drug & Alcohol Testing

Whether for pre-employment, court ordered, reasonable suspicion or by parents for their children — drug testing works as a strong solution for a variety of issues.


Grand Slam Investigations can assist you with all of your drug testing needs. We work with both DOT-regulated and non-regulated businesses, health care agencies, non-profits, athletics associations and even parents.


For many businesses, workplace drug testing remains standard to reduce liability, increase productivity and keep drugs users out of the workplace. To help employers get the information they need to make smart decisions, we offer programs and support for pre-employment drug testing, random drug testing, post-accident drug testing and drug-free workplace programs.

Did you know that:

  • 75% of all drug abusers over the age of 18 are employed
  • 80% of them steal from their employers
  • 65% of all work related accidents are due to their drug use


You must not assume the employees in your organization are immune to the problem of drug and alcohol abuse. Grand Slam Investigations will help you implement a drug-testing program in your workplace or in your home. We even offer a wide range of drug testing products that can be purchased online through our website. Click here to see our drug testing products.
