Now It's Legal..

 

 (imdb)

THE TERRIBLE TRUTH-1951-Scare film about marijuana leading to heroin addiction, through the eyes of Phyllis, a nice high school student who starts smoking “reefers” with some guys “who have no backbone”, then meeting Phil the pusher, who makes her a heroin addict/pusher who later goes “cold turkey”. An on-screen narrator William B. McKesson suspects “the Reds” might be behind it. This short (around 10 minutes) is so cheap and haphazardly made that all his dialogue was dubbed later and his words don't match his mouth movements. 

Once a stand-in for John Wayne, Sid Davis produced many similarly themed exploitation shorts (LSD: TRIP OR TRAP!, GANG BOY, THE BOTTLE AND THE TROTTLE). He also directed a few including NAME UNKNOWN which also featured William McKesson, who was an actual juvenile court judge.

Thanks for reading!
