Thanks for writing to us.

Smoking marijuana three months ago is a long time gap to show in your hair follicles that too in such a small quantity- only three hits.

You need not worry about marijuana showing up in your hair follicles of chest.

A standard hair follicle screen covers a period of approximately 90 days. It is only rare that they examine a longer length of hair for more past history. The metabolites of drugs accumulate in hair follicles in detectable quantities only on a long term and high dose use.

I hope this information has been both informative and helpful for you. If there are additional concerns, I am available for your followups.
