Aaron Lachant has been at the forefront of the marijuana industry since 2009. By solving novel and complex regulatory, compliance and licensing issues, Aaron has kept his clients, including approximately 45 of the 135 originally legalized dispensaries in Los Angeles under Proposition D (legislation he co-authored), in business and flourishing. Combining Aaron’s pioneering experience getting marijuana businesses permitted with his adroit navigation of a regulatory landscape in flux, has made him the go-to attorney for legal cannabis advice.

Cannabis Industry Counsel and Trusted Advisor
He frequently acts as outside general counsel for clients in the industry and is active in the Greater Los Angeles Collective Alliance (GLACA), an association of medical cannabis cooperative and collective operators whose mission is to provide safe access to patients with adherence to a strict code of operational guidelines. He is the only attorney appointed to the Los Angeles County Advisory Working Group on Cannabis Regulation. Aaron also heads the consulting group, MMLG, which focuses on navigating local and state licensing application requirements for cannabis-related businesses.

Focused on the Marijuana Business
Well ahead of the curve on the issues facing the marijuana business, Aaron’s work has grown with the maturing of the industry. He has worked on many sophisticated corporate transactions, advising clients on M&A deals, partnership disputes, and litigation involving regulatory violations. His legal knowledge of business and regulatory issues confronting the cannabis industry is complemented by years of experience representing other healthcare providers in all aspects of healthcare law. With the legal marijuana market expanding at a rapid pace, Aaron’s practice is devoted to keeping marijuana businesses open and consults with regulators in various jurisdictions to keep laws favorable.

The Daily Journal named Aaron one of the Top 40 attorneys in California under 40-years-old in 2018. The Legal 500, one of the premier legal research, ranking, and publishing firms in the world, recognized Aaron for his “cutting-edge work in the cannabis space.” Similarly, the Los Angeles County Board of Supervisors commended Aaron for his service on the Los Angeles County Advisory Working Group on Cannabis Regulation. Aaron has been recognized by The Best Lawyers in America (2020-2024) for his healthcare litigation practice. He has been selected to the Southern California Rising Stars list by Super Lawyers every year since 2018. Additionally, Aaron was named by his peers as “Lawyer of The Year” for Litigation – Healthcare. This is a significant honor: only one lawyer per practice area in each region of the country with the highest overall feedback from their peers is awarded the “Lawyer of the Year” honor. Only the top 0.4% of lawyers earned this exceptional distinction in the 2023 edition, placing Aaron in elite company.

Life Outside the Firm
When he is not helping to keep (legal and permitted) drugs on the streets, Aaron spends his time rooting for the Syracuse Orange and exercising with the Los Angeles Rowing Club. He enjoys writing, traveling, playing the piano, building guitars, and sous vide cooking.
