Good Alcohol/Drug Medical Education Class for EMTs?

[Talonrazor]

I am looking for some additional training to present to my EMTs that work me. We are an EMS agency based out of the city jail that handles drug/alcohol/psych AMS detainment.

Anyone know of a good class, video series, power-point presentation or certification that deals with alcohol and drug usage? BLS level is ok, something that gets into the pathophysiology would be ideal.
