The answers to this question are rather hilarious. Some have merit (though without any factual sources, which is pathetic, considering how many people who answered are lawyers, cops, and other people who should know how important citing sources is).
Whether or not you think it’s bad to sell drugs depends on your perspective on life. Drugs obviously exist, and one could argue the crime surrounding them surrounds them because they’re illegal, and that is somewhat true about the black market.
There’s an illegal black market around batteries too (phone, car, any type of batteries are valuable). Tons of crime involves gold and diamonds. Many criminals fraudulently recreate legitimate items such as Beats headphones: Cheap Beats and How to Spot Fake Beats | Safe Buying Guide
Because there’s crime around Beats headphones, does that make it bad to sell headphones? Many criminals listen to music – hell, some inmates even had the nerve to film a rap video: Rapping inmates get solitary confinement for almost 20 years
Anyone who’s ever worked in the music business can tell you it’s dirtier than the drug game.
There’s nothing wrong with selling drugs. It’s a moral choice, and if you don’t make it, thousands of others will. None of the rest of these answers even cite their sources, instead offering opinions and hoping their credentials will legitify such an opinion as fact – it doesn’t.
Selling anything on the black market is dangerous. Selling anything on the legal market is dangerous. Having anything of any value is always dangerous – that’s nature. Singling out drugs is just some weird thing old people do when they’re delusional and in denial of the facts and realities of life.
