i like the witch hunt idea, random testing, but what this company is doinfg is purely civering its as. ther is no preventative measure, and even if they test possitive i would say that marijauna and alchohol is acceptable (but grudgingly) as long as it does not effect you at the moment of work, give them one of those 10 minute reflex and aptitute tests i have heard about, (not sure where, drived ed teacher maybe) it is a simple thing on reflexes ,rapid questions, motor skills...uh oh, the bell, lunch is over i g2g i'll finish dis l8ter
