Could YOU pass a hair strand test if done meth 84 days ago?

You may or may not pass the hair strand test depending on the length of your hair and which strand they take. A long hair will grow in your head for years so something that happened 84 days ago would still be in your hair. On the other hand, if you only took it once 84 days ago, that would probably be so little compared to a total hair that it would be hard to measure.
