If i took a few hits from a joint over 14 months ago, will it show up on my hair follicle test? i also have really long hair if that helps.

Depends: If they check the hair follicle, the test should be negative. But if they check further down the hair shaft, it may be positive. After 14 months a single exposure to marijuana should show up positive at about 17 cm (assuming normal hair growth). If that was the only time your used, hair on either side may be negative. In fact this type of analysis is used to establish history of episodic use.
