No more secrets as hair tests set to expose drinkers’ habits
Scientists have developed a range of hair, blood and urine tests which can show how much someone has drunk over the past days, weeks or even months. Alcohol disappears from the body within hours, but drinking produces chemicals which stay in the body much longer.
New Scientist magazine says doctors and employers may use the new tests. There are already tests used to show if someone has been drinking, but most rely on indirect evidence such as the level of liver enzymes in the blood. But the results can be affected by other toxins, and even pregnancy.
