No longer are devices just to show your where abouts, they transmit information via the computer as to your body alcohol content as well....but they are still not perfect yet at this article written by a doctor states...and he has his own reservations about how the product is used....BD
Like most patients assigned to my substance abuse clinic these days, John, a stylish 22-year-old cosmetology student, did not arrive voluntarily.
Scram, for Secure Continuous Remote Alcohol Monitor, records the wearer’s alcohol intake by measuring air and perspiration emissions from the skin every hour. It detects blood alcohol levels as low as 0.02 percent, which corresponds to one drink or less an hour, and can even tell when the alcohol was consumed. Once a day, John has to be near a modem so it can transmit data from the last 24 hours to a monitoring agency and his probation officer.
False positive readings are also a risk. Among other things, baked goods like raisin bread and sourdough English muffins can cause the body to produce its own alcohol. And like any computer-based device, the Scram can malfunction. The culprit was a five-month buildup of sweat and dirt on the sensors. There have been no false alarms since the device was thoroughly cleaned.
