It's not sold, marketed, or regulated as an addictive substance though, which is a huge fucking problem and a big part of the issue.
They sell it in little bottles as an "herbal energy supplement" on gas station counters, right next to the 5 hour energy drink. Some companies basically market it as a health tonic.
I'm all for people doing what they want, but the industry intentionally makes that hard do so in an informed and responsible fashion.
