Apparently these hair follicle drug tests go back six months and who can prepare for that? I've smoked pot about 5 times within the past 6 months each time was about 1-2 hits... can I past this hair follicle drug test? Last time I smoke was about three weeks ago...

In all likelihood you will pass a hair drug test (HDT). Infrequent cannabis smokers are seldom detected.

The testing industry's promotion of HDT is the best thing that ever happened to low and infrequent users. Now they can continue smoking while having a official source certify that they don't.
