The Diff'rent Strokes Episode Where Michael Oliver Was a Junkie!

One of the most famous episodes of Diff'rent Strokes was the one where first lady Nancy Reagan stopped by Arnold Drummond's grade school to give an anti-drug talk. Michael Oliver was a drug dealer in that episode! Here are some screen caps from the episode where Oliver was trying to sell uppers to Arnold and Dudley. I heard that Oliver was arrested for drug dealing after this episode was filmed and sent to a juvenile detention facility for several years where sadistic homosexual prison guards passed him around as candy. Does anyone know if that's true?
