Bonanno's number one since Vito Genovese fall, and the later Genovese crime family leaders made efforts to get away from narcotics. The Lucchese were also big in it, which help the FBN grab some informants from that family.
Today it would look like this.
1. Bonanno
2. Gambino
3. Colombo
4. Lucchese
5. Genovese ( they would be higher on the list if we are only talking about financing narcotic shipments)
