SCRAM devices can tell the difference between consumed alcohol and alcohol in the environment. In some cases, defendants have tried to trick the system by spilling a drink on it or otherwise exposing it to alcohol. While this will cause a “spike” in the bracelet's data, it will show a different pattern than consumed alcohol. However, you must sign an agreement not to use products containing alcohol on or around the bracelet. Accidentally exposing the device to alcohol will not generally be considered a violation. But intentionally trying to trick the device can subject you to court sanctions.
