Question by Matthew M: What different types of drug tests have you endured for an employer?
I have usually had urine tests but today I got a drug test for my new job and they did it right at the store. They used a cotton swab and i had to hold it in my mouth for 6 minutes then wait for a boring test. Anyone else ever have the cotton swab test or any other type of test?
