The sale of kratom is really taking off in South Dakota, but if you still aren't familiar with it, you no doubt will be soon. Millions of people take the substance derived from the leaves of a plant from Southeast Asia, either in capsule or tea form for a variety of health reasons.

Proponents have a powerful lobby behind them; so powerful that when the DEA wanted to make kratom a schedule one drug, public outrage made the government agency change its mind.
