How long does the detection period for a drug test via hair last for alcohol?

Question

I drank a few bottles of Vodka and beer in the past 3 months.

Answer 1

hair holds evidence for literally years.

Answer 2

Sorry yet someone gave you the incorrect assistance. Hair checks will stumble on use interior the previous 6 months for the reason that your very last use and not in basic terms 3 months. in case you smoke "randomly", what's to shop your father from randomly picking the subsequent day for the finding out?

Answer 3

i know hair tests can show pot use for as long as you have the hair, depending on length but i didnt think they used hair for alcohol...
