Joe Bonanno, drugs or no drugs?

drugs.

I can't figure out why he wasn't nicknamed Joe Babania instead of Joe Bananas.

Bananas wasn't where he made most of his money.

I think he and many of his capos were up to their eyeballs in it (junk). Being a smaller family with less territory made him greedy to obtain concentrated wealth. Drugs was the answer.

I think he was so greedy that he was behind Carmine Galante's rise and neither of them wanted to share their profits with the Commission.
