Sam’s Club is owned by Walmart, which states on its website that successful job applicants may have to take a drug test in the pre-employment phase. It’s reasonable to expect that the same policy applies to Sam’s Club employees.
In addition, several Indeed users note that Sam’s Club makes employees take a urine test, as part of a random drug testing policy. In a nutshell, if you want to, or already work at Sam’s Club, prepare to get tested!
