I am extremely impressed with the National drug and alcohol screening association. The website, ndasa.com, offers an abundance of resources that have been invaluable to both me and my employees. I appreciate the emphasis on education and best practices when it comes to drug and alcohol testing. The association's dedication to ensuring a drug-free workplace is truly admirable. I highly recommend the National drug and alcohol screening association to anyone in need of drug and alcohol testing information.
