In 2015, identifying an emerging demand for operational experience, innovative solutions, and genetic advancements, Leif co-founded Catalyst BC, a cannabis advisement firm that guides partners through the gauntlet of conceptualizing, funding, designing, building, and operating a profitable cannabis or hemp business. During the first year of operations, Leif helped a client obtain one of Maryland’s first fifteen cultivation and dispensary licenses. Since then, the team has helped secure more than 46 licenses for cultivation, manufacturing, and retail dispensaries in 8 states, including some of the most competitive and rigorous application processes to date.

Together with Catalyst BC, Leif and partners have developed multiple ancillary companies, such as Allele/303 Seeds, a genetics service and solutions company with an extensive portfolio of proven and proprietary cultivars, and Greenhaus Industries, the first commercial vertical cannabis cultivation company. Greenhaus Industries was acquired by Pipp Horticulture in 2018, creating the industry-leading vertical farming solution with over 2,500 grow rooms worldwide. In addition to his ancillary endeavors, Leif was Supply Chain Manager for FLRish Inc. and Harborside Health, one of the most prominent medical and adult-use cannabis dispensaries in the United States.

Maryland Cannabis Lounge Laws 2026: License Rules and How to Prepare

Maryland’s adult-use cannabis law (July 2023) authorizes on-site consumption lounges, but the regulations are still developing. The 2023 Cannabis Reform Act created “On-Site Consumption Lounge” licenses, akin to food-service venues, where cannabis can be consumed on premises.

Illinois legalized adult-use cannabis in 2019, but social consumption lounges are governed at the local level.

DC Cannabis Lounge Laws Explained: Private Club Compliance & Strategy

In the District of Columbia, cannabis use and possession by adults 21+ is broadly decriminalized, but retail sales remain illegal due to federal restrictions. Unlike jurisdictions with regulated adult-use sales, D.C. has no state-sanctioned retail market, which means there is no official license for public consumption lounges. Public consumption of marijuana is explicitly prohibited under D.C. law (fine up to $100) and the city has only considered private club models.
