evidence: "Today at work a patient had a Red Bull. [I] told him they [test positive] on drug screens. He didn't believe me. So I had him pour some in a new cup, and it [tested positive] for [methamphetamine] and [oxycodone] and [buprenorphine]. Also Bang will [test positive] for [ecstasy/MDMA]." [...] The first point to clarify is that neither Red Bull nor Bang nor any other energy drink contains methamphetamine, buprenorphine (often sold as suboxone), oxycodone (often sold as OxyContin), or MDMA (commonly known as ecstasy or X). What the meme alluded to (whether knowingly or unknowingly) was the phenomenon of false positives, in which a drug test incorrectly indicates the presence of a substance that is not present, either in a biological specimen (usually urine and blood) or a sample of the substance in question. The ingredients of both Red Bull and Bang can be found listed here. [...] The second misleading feature of the meme is that Rider Freese said she used a urine screen test to screen for methamphetamine, buprenorphine, and oxycodone in a sample of Red Bull. This makes little sense, because that kind of test is used to screen for illicit substances in a person's urine, not in a beverage.
