Hello,
Thanks for your query.

I appreciate your efforts for medical consultation in so much distress.

Cocaine is fat soluble substance. If it remain in skin contact for long time like in human hair weave, then it can be absorbed through skin in body. Now few medicines are also coming in market as transdermal patch which absorb through skin (like estrogen transdermal patch) using the same mechanism.

Amount of absorption depend on following factors:
-Amount of cocaine present on scalp
-Duration of contact to skin
-Presence of inflammation (redness) of skin: it increase absorption.

Most of cocaine is metabolized by the liver with very little unaltered cocaine being released through the urine. Urine drug tests measure the existence of cocaine in the body by detecting cocaine metabolites (benzoyulecgonine and ecgonine methyl ester). The identification of these metabolites can be detected four hours after use and will continue to be detectable for eight to ten days.


Please accept my answer in case there are no further queries and recommend our services to your friends too if you have found it helpful.

Wish you good health.
Regards.
