In your own experience how are you measuring the g of the people you know? It is really dangerous to rely on the people you know to predict causes since the people you know are not a good cross section of the population. It is like people who say how did politician x get elected when everyone I know voted for his opponent. For what it is worth my personal experience is that the use of drugs or alcohol are not closely correlated with my estimate of a persons g, but major abuse problems are quite negatively correlated.
