I assume you've see this sort of thing among those in sales are your company, yes? Is it coke or all kinds of things? And any idea why? Is sales particularly stressful or somehow more intense than the tech side of things?
As someone who's also seen this pattern: I'd say the type of personality that is good at sales just correlates strongly with the type of personality that enjoys cocaine. Stress level or intensity can be high or low (within limits) in either occupation.
