Our time is limited so you might answer at the same time to what I asked earlier. Seven minutes are very short.
It is my impression that drugs are so lucrative for the large criminal organizations — those are the most violent or that establish their discipline through violence — that they leave to other groups activities such as cigarette smuggling or even prostitution.
In fact, there are many other criminal organized groups but ultimately drug trafficking is so lucrative for the more dangerous large criminal organizations like the Hells Angels or even the mafia that they let those others thrive next to them.
