“Here’s the first one,” Elliott Klug said as he reached into a soft-sided briefcase and handed over a tax document and manila envelope filled with more than $3,000 in cash. Klug stood in front of the counter facing a Colorado official to pay taxes for Pink House, the chain of marijuana stores he founded.

Despite his laid-back appearance, which features a straggly ponytail and mutton chops, Klug’s money was neatly bundled in stacks of $,1000 or $2,000, sorted by denomination; all bills faced the same way. “I guess I’m OCD or something,” he said with a chuckle. Klug had trained his staff to organize the money this way to enforce precision. “I hated going somewhere and finding out I was $20 short,” he explained.
