Been to Europe for training by manufacturers, job creators.  Several large pilsners at lunch were just shy of mandatory, laughing at the American was involved.  The U.S. is very prudish regarding drugs and sex.  It's about use vs abuse.  Worked for a U.S. manufacturer when the law declared employers must have written drug policy.  "Drug abuse in the workplace will not be tolerated." was the result.  Simple. Practical. And met the criteria of the new law.
