Financially, I am sure his family will be fine. If he really didn't save anything, I am sure they could sell his airplane and Bentley for a few extra dollars.
To say that he was always 'coked out of his mind' is likely assumptions. People do have a lot of energy, they can keep a facade on when in front of the camera. All we see is a 30 second to 3 minute commercial. In the 'Pitchmen' show he seemed to be very reserved and calm outside of pitching.
Everyone has their demons and vices, maybe Billy Mays' was coke. There are plenty of high up people (celebrities, actors/actresses, athletes, CEO's etc.) that have vices and use drugs, and probably even more than the next guy.
Bottom line is, its still tragic that he died relatively young, regardless of the circumstances and the situations surrounding his personal life.
