No, Lidocaine isn't listed as being known to cause a false positive for anything.

Did this happen to you?

High doses of it have been known to cause a false positive for Cocaine, since they are distantly related, but you usually don't absorb enough from the patch to have it be detected as anything.

Well which is it? Lidocaine does not cause a false positive for anything... or High doses have been known to cause false positives for Cocaine? You are contradicting yourself and therefore not looking to credible to me. If Lidocaine has been known to cause a false positive for Cocaine, at any dosage, you should state that and leave it at that.
