I don’t know about where you live, but here the drug lords owns some territory. And within that territory, they take political actions like closing the nearby churches, for example. I think selling actual medication could serve their purpose very well. They already sell smartphones for a low price to the local people ($15).
Planck units are the smallest packets of something, which is called quanta. Planck discovered he could get more accurate measurements if he separated the energy from radiation in small packages, which proved useful for other theories later.
