My question was, "if you failed a drug test for a company that tested through DISA, what could you do to make yourself eligible to be hired?" There was a response that said you could call DISA, pay $500 and set up counseling and retest, but it didn't give the number. I would like to know specifically who to call. Thanks.

I'm not familiar with who provided you with the information but here is a link to DISA so you may contact them directly:

Employee Drug & Alcohol Testing & Screening Services - DISA (http://www.disa.com/employee-drug-alcohol-testing-screening-services.html)

281 673 2400 blow off the options and press 0.They will ask for your information and send you a form email mail or fax.Return the form with $550 and they will set you up with a consultation in your area.It can be as simple as a twelve step or worse depending on the people you see.Quickest he said takes 2 weeks,I just got off the phone with them.National SAP is who set up your rehab,their number is 800-879-6428.My mistake earlier SAP will send you the form,disa only refers you.GOOD LUCK

Of course the issue now will be, they already have you under the "failed" file, They know you failed before,

Why would the company even reconsider?
