I work in the ER part of the time and we'll see patients, usually younger (20's) but sometimes older that are acting completely intoxicated, yet their triage drug screen will come back negative for everything we test for (opiates, marijuana, Tricyclics, benzos, barbituates, amphetamines, meth, PCP ....there might be a couple more)
Any ideas as to what is on the streets these days? I'm heard that dextromethorphan is something being abused. In large doses it causes paradoxical effects (hyperactivity, etc.)
What have you all seen?
