Question 8

In Texas,a man showed up at a medical facility claiming that he felt drunk when he had not ingested any alcohol.Indeed his blood alcohol measured 0.37,many times the legal limit.Although he was a home brewer,he claimed that this intoxication had been happening often without his drinking any alcohol.Which of these hypotheses and actions might be most useful in diagnosing this problem?

Accepted Answer

A)  His home brew concoctions have created a type of alcohol that lasts a long time. Have him refrain from home brewing for a week and recheck his blood alcohol.
