NYC Drug Kingpin Turned Weed CEO
This week on The Hidden Third, Mariana sits down with Coss Marte — a former drug dealer who, at 17, was running what he claims was New York City's first 24/7 drug delivery business, pulling in over $2 million. A betrayal within his own team brought it all crashing down, and he was suddenly facing up to 25 years in prison. Behind bars, a doctor told him he wouldn't survive to 30. What happened next changed everything. Coss lost 70 pounds, built a workout program with fellow inmates, and wrote the business plan for ConBody — a gym empire built on second chances. Then came the ultimate full-circle moment: he's back to selling drugs — this time legally. His cannabis dispensary ConBud now operates multiple locations across NYC, including one on the very corner of the Lower East Side where he once dealt illegally. From drug kingpin to CEO, this is one of the most remarkable reinvention stories you'll ever hear. Learn more about your ad choices. Visit megaphone.fm/adchoices

Kari Ferrell became known as “The Hipster Grifter” after her cons went viral. In this episode of The Hidden Third, Kari joins me to talk about how her scams worked — from bad checks to stealing from friends and lying about being a cancer survivor — and how things escalated after she moved from Salt Lake City to New York City, where she landed a job at VICE.
We dig into what was driving her at the time, how easy it can be to manipulate trust, and what it’s like to become a public villain on the early internet.
