Mr. McCain has been recognized as an expert witness for drug and intoxicant cases in The Commonwealth of Pennsylvania. He is extensively experienced in a wide variety of analytic techniques including LC/MSMS, GC/MS, GC, LC, a variety of automated platforms and even the antiquated technique of Thin Layer Chromatography (TLC).

His work and personal history has provided some invaluable insight into the importance of the testing performed at Apollo Laboratories.

He will state he has been doing drugs, professionally, for over 40 years.
