It will depend on how long it has been since the drugs were used. They can take a sample of hair and test it from root to end. There are places that will "wash" your hair but just know nothing is %100... Thanks, DefTone

Can possible future job opportunities become ended due to DISA information positive hair follicle test?

Yes, depending on the job and depth of testing. If the potential employer doesn't allow a history of marijuana use and the hair tested is long enough to prove a history of use then, of course, the future job opportunity is in jeopardy but if your future employer cannot prove a history of use when testing a hair follicle or cannot produce a hair follicle long enough to show your history than no, you can't lose future employment from a DISA hair test.. In other words, cut your hair and shave your body if you use enough to worry about the test...
