Many popular depictions of American soldiers in Vietnam show them smoking marijuana and using heroin while deployed. But how common was drug use amongst American servicemen in theatre? And was the high command aware of this and were any measures taken to stop drug use?

I'm thinking of movies like Apocalypse now and I also have a vague recollection of a documentary showing American soldiers smoking weed through the barrel of a shotgun.
