Profaci was not a drug trafficker. He was the "olive-oil king". A multi millionaire. No need for him to go into drugs. He was extremely devoted to his businesses. There´s very little info on him which shows how low key he was. Did he use his connections/muscles in order for his businesses to flourish? Absolutely! Was he a murderer? Absolutely! But a drug trafficker he was not.
Capeci also seems to be convinced Profaci was involved in drugs. And Profaci being a multi-millionaire through legit business isn't a reason to assume he wasn't involved in the drug trade. It didn't stop him from being involved in many other crimes, up to and including murder.
Nothing seems to suggest that he was involved (evidence wise), other than that passage above posted by Alfa. But the way I see it, is that we shouldn´t jump to the conclusion that he was due to that we don´t know where that passage has its origin or what it was based upon. Let´s just agree to disagree.
I remember once reading about Profaci´s farm in NJ. Apparently there was a takeoff and landing strip for airplanes located on the grounds. I think I read this in a book and the author was very fast to conclude that the landing strip was used by Profaci to smuggle drugs. How absurd! All that was missing in that ridiculous story is that Profaci himself flew the aircraft and used Magliocco as his copilot. My point is that a lot of stories avialable is pure rubbish.
One thing that may be of interest is how and why Profaci became close with Joe Bonanno. Rosalie Profaci, daughter of Salvatore (Profaci´s brother) and wife of Bill Bonnano explains this in her book
Mafia Marriage:
"Canada was a main source of illicit liquor at the time, and illicit liquor being a staple of my uncle Joseph’s and Stephen Magaddino’s incomes, I suppose arrangements for bringing my father into the United States from Canada were not difficult to make. It was Joseph Bonanno, Stephen Magaddino’s cousin, who was sent to Canada to ease my father’s way. When Mr. Bonanno met my father, they were both young men in their early twenties. They did not go directly back to New York, but spent a couple of months living and working together at bootlegging in Buffalo, so that by the time Mr. Bonanno delivered Joe Profaci’s little brother to him, not only had a friendship been forged, but a lasting alliance in their world."
