Drug dealing is a business, probably not the most moral of businesses out there, but certainly not the worst. When you look at the money at stake, the opportunities, the market and all the little perks that come along with the industry, such as working for yourself, no tax, cash in hand...well there's small wonder why so many people choose to deal class A and B drugs.
The consumers are at fault here. They give the dealers their money and often ruin their lives and their finances in the process. If they had a little bit of discipline, they'd get their highs through cleaner habits.
At the end of the day, fast food, cigarettes, alcohol, hookahs and excessive eating are all hazardous. The Asian dude round the corner to me serves the most greasy, disgusting fried chicken burgers I've ever seen, and I'd sooner smoke a cigarette than ever scoff down one of those abominations that some call food. But I can't blame the fella for selling that stuff since others willingly devour it without thinking twice.
