How Long Does Marijuana Stay In The Body?

I smoked 2-3 hits of marajuana 30 days ago and then had to take a hair folicule test. The last time i smoked prior was over 2 years ago, and never was a heavy smoker anyway, maybe 5-6 times a year. will what I smoked 30 days ago be enough to show over the cut off level and fail?

Addiction Medicine Specialist 's  Response
It's more the level of the hair than the amount of marijuana. While that is not a lot, it gets into the hair. If the hair was growing at the time of smoking then that particular part of the hair will have marijuana metabolites inside of it. Hair grows maybe one inch a month, so, 30 days ago would be quite close to the scalp indeed.
