There are still american mobsters heavly involved in drugs today?
Not one or two kilos but high quantities.

I don't think so, they are not among the alleged drug kingpins that sit on the top of the drug trafficking chain.

There's probably a few, but not many. Maybe some of Johnny Gambino's guys are still involved. Vinny Basciano and his people were major dealers well into the 2000s. It's hard to say what's going on right now

It's hard to say, until that big blockbuster indictment comes out and catches everyone by surprise.

That Greek guy John Venizelos, also known as “John V,” “Big Man” and “John from Staten Island,” an alleged associate of the Bonannos was a major Staten Island-based distributor of narcotics for a Canadian narcotics trafficking enterprise. Ten years ago they were charged with trafficking over $1 billion worth of marijuana and cocaine in the United States.
