Its funny you mentioned coke because i know 1 doc and 1 pharma rep who both told me the long hours and detailed work breeds cocaine use
Mike I had a prosthetic heart valve sales rep I managed die of an overdose of cocaine and alcohol. He was an ex marine, well educated and made as much as the surgeons. Still out spent his income, had huge debt and his marriage was falling apart.
I also had a friend in the industry who was a vp of sales and he too died of an overdose. I think the corporate world and high pressure jobs take a toll.
