Has anyone heard of dental procedures causing positives for cocaine in a drug test?
Local anaesthetic Lignocaine is N-diethylaminoacetyl-2,6,xylidine hydrochloride, but I do not think it contains cocaine at all, or in any quantity that would show in a blood or urine test later. Lignocaine,xylocaine and other similar products are used by Dentists to deaden nerves during dental procedures.
Reply:I havent heard of that. unless any narcotic pain killer was priscribed.
Reply:I have never heard of anything like this.





You can always call and talk to your dentist if you feel it was something that he may have used.
Reply:no. am not aware if they still use cocaine for dental use nowadays.
Reply:never heard of that but the anasthetic dentists use is from the same source as cocaine so its probable that this was why it was detected in your drugs test.
Reply:it would not show up as cocaine, the anasetic they used to use was part of the same family but nowdays it is not, i would insist on being tested again but get your dentist to write to your firm and tell them what you had done good luck
