How many states use Secure Continuous Remote Alcohol Monitor (SCRAM) which continuously track wearers through trans-dermal monitoring of alcohol content in their body?

A SCRAM is a trans-dermal alcohol monitoring system that is used to monitor the alcohol consumption of people who are on probation or parole. The device is worn on the ankle and it tracks the wearer's blood alcohol content (BAC) levels. If the wearer's BAC exceeds a certain level, the device will send an alert to the monitoring agency.

As of 2019, SCRAM is used in over 2,500 counties and jurisdictions in the United States. However, no states use SCRAM to continuously track wearers through trans-dermal monitoring of alcohol content in their body.
