Analyze cocaine levels in hair follicle drug test
« on: September 17, 2017, 11:58:52 PM »
My ex just took a drug test and I am curious as to what all of the levels found in his hair follicle mean as far as how heavy of a user he is and any other helpful bits of information you can give me about his results. Thank you!

Benzoylecgonine: 4281 pg/mg
Norcocaine: 71 pg/mg
Cocaine: 7495 pg/mg
Cocaethylene: 95 pg/mg

There are a number of historical threads on this and similar topics - try searching for e.g. benzoylecgonine

Extracting hair with mineral acid ([HCl] or H2SO4) is a pretty efficient method.
