Please can anyone help??
Family member has just failed a hair strand test, he has not smoked in 6 months but has been in company of thoses that are and has ''handled'' it.
He is average /slim build, 5ft 7in and exercises 5 times a week, hair is very coarse.
Do you need to know anything els?
Would the fail be because of 2nd hand smoke or can it get in to his system from handling it?
I would be very grateful of any help
