No it can't.The test looks up to 90 days history of usage.
Each half inch goes for 30 days history approximation.
Any lab will not test for hair longer than 2 inches.

The hair drug test is very good at detecting drugs.It can't tell how much exactly but it's enough that if you do it your gonna get caught if tested.The time period varies with different drugs.But you can be sure that it is at least a month of staying away from it that you need to do if you don't want to be caught doing something you shouldn't do.

Are you talking about cigarette smoke or something else. Hair follicle tets can reveal consumption of certain drugs. Google "hair follicle tests" for more concrete information.
These type of tests can be used in child custody cases or criminal cases to determine whether someone has been using illegal substances.

It can tell if you've done drugs in the past year. I think what your talking about is a hair folicle test

Nope,but it can determine everything you've done and there's no way to trick the hair test.

Yes one centimetre of hair represents one week............... so if you smoked pot 4 weeks ago then stopped for 2 weeks and smoked last week then it would show up one centimetre from the scalp then 4 centimetres..........
