Transdermal Alcohol Monitoring in Arizona

Transdermal Alcohol Monitoring in Arizona is a practice that is the can often produce false positives. Since their invention, electronic bracelets that monitor a person’s alcohol consumption have increasingly been used by judges to prevent those convicted of drunk driving from consuming any alcohol at all for a given time. These devices, which are strapped onto the ankle, are able to detect small amounts of alcohol through a person’s sweat, and violations are reported to the individual’s parole officer. However, as reliable as the courts claim such devices to be, they have been subject to little scientific testing, and as some have found out, false positives remain a real possibility.

How Do Transdermal Monitoring Devices Create False Positives?

For someone who has been wearing an ankle bracelet and abiding by its restrictions, the possibility of facing punishment for a violation that they did not commit is infuriating. Because of the device’s perceived reliability, it can be difficult for an innocent person to prove that they are not at fault. Less is known about what creates false positives than we would hope, but the following may be responsible for false positives on these devices:

  • Raisin bread
  • English muffins
  • Sourdough bread
  • Hairspray
  • Sweat / dirt buildup on bracelet

According to an article in the Northwest Florida Daily News, even SCRAM bracelet inventor Jeff Hawthorne has admitted to the possibility of false positives in a case that involved a 17-year-old girl who received a false positive after being exposed to hairspray.
