I've known a number of stoners. None of them were able to accomplish anything until they went to rehab and got off the drugs.
Locutos just ruined his life. Too bad he has parents who enable him.
We had a machinist at our shop who could only work stoned. He was so hyper when he wasn't stoned that he couldn't stand still for two seconds.
He would smoke before work, at break, lunch and the afternoon break every single day. The boss knew about it, but his work was good and he always showed up on time. He lasted until the company implemented random drug testing and quit before he ever got tested.
