England has implemented a sobriety ankle tag scheme in which people whose offences are related to alcohol will be eligible for an ‘alcohol abstinence order’. Whilst on such an order, the tag wearer’s sweat will be tested every 30 minutes for signs of alcohol use. A positive test will cause an alert to be sent to probation services. Positive tests for alcohol could then mean a breach of the order and increased sanctions. The scheme has been running in Wales since October 2020 where it has reported a 95% compliance among wearers.
