but Chino is not really the ideal example for the point you made there.
He had tons of fun with his band over the years, probably banged a lot of groupies, toured all the continents of the earth and made some nice money as well. And even considering the downsides of all that, the divorce, not seeing his kids for long episodes, its the life he chose and its a really good one. Not everyone does drugs like cocaine or weed to cope with something, for some its just fun to blast themselves away, and I imagine it would be a lof of fun after performing in front of an audience.
