The Opioid Addict on the Trading Floor

Wall Street professionals get hooked, and some executives see an opportunity.

When things got bad for trader Trey Laird, he was drinking alone after work and doing cocaine on the evening train to Connecticut. But his biggest problem was swallowing about 160 milligrams of OxyContin every day. He spent his time high, thinking about getting high, coming down or running out of his Lazard Capital Markets office in Manhattan to meet a dealer.

Laird, 47, has been clean for six years and is in a different business. In January 2016, he opened a luxury sober-living home in a mansion in Darien, Connecticut, one of the richest towns in the U.S. His company, the Lighthouse, opened a second branch this year in nearby New Canaan. A bedroom there costs $12,500 a month with a roommate, or $15,500 without one.
