The last time I did cocaine was on Feb 9 2014 and have a drup test in about a week July 8 2014. I am a 32 year old male 170lbs and haven't touched a drug beside what the doc gave me for high cholesterol. Will the cocaine so up in a hair test? My hair is about 1.5 inch now cut from about 3inchs a month ago for the interview.

You should be fine. Hair from the head will only show the past 3 months of drug use.

The length of hair extracted and used will conform with what is believed to be three months. Your milage will vary depending on your hair growth rates. That being said, the test in question is for habitual use. Non-habitual use will not deposit enough of what they're looking for to go above the limit they're looking for.

If your drug use in the past 90 days is zero or relatively low than you have nothing to worry about.
