Basically, we haven't seen a lot of use of alcohol bracelets, but they are transdermal. They fit against the skin and collect samples of the sweat that comes off the person's leg. They can actually take a reading fairly quickly once the alcohol has been absorbed into the bloodstream and into the body fluids.
Those devices have a lot of merit. There are a lot of them out there in the U.S., but we have not seen any particular programs in Canada that have taken the lead and decided to implement that particular technology as yet.
