Yes. Vito Genovese was into that. Some Genovese family members remained involved in that after he got busted, though it was more discreet due to a policy change. When the heat started turning up on the US Mafia, the Sicilians started handling distribution for them, making the US families' involvement in the background less obvious. Similarly they have sometimes used non-Mafia groups as supply sources or distribution fronts.

Small businesses were often used as fronts. Maybe still are.
