Outside the Office

Karen is an adventurous traveler, backpacker and off-roader.

She has independently traveled, mostly solo, to over 100 international cities, from the jungles and temples of Southeast Asia and Central America to the high mountain passes of the Himalayas. She enjoys shipwreck diving and cooking. Her favorite place in the world is the cabin she helped build on the coast in Big Sur.

Community Leadership

Karen donates her time, talents and legal skills to pro bono matters.

Karen represented a large cohort of physicians and clinicians in their amicus brief in AIMS v DEA, a landmark case in the 9th Circuit Court of Appeals that involves a direct petition to the DEA to reschedule psilocybin from schedule 1 to schedule 2 of the Controlled Substances Act.

Karen serves her community though leadership roles in multiple non-profit organizations. Karen is a member of the Board of Governors for Womens Law Association of Los Angeles, and California Women Lawyers.

Karen is a founding board member of the Women in Psychedelics Network, a non-profit organization connecting women professionals working to advance research and development of psychedelic therapeutics.

Psychedelic Therapeutics

Karen Luong follows the research and development of these medicines for psychiatric conditions such as PTSD and treatment-resistant depression.

While psychedelic drugs such as MDMA, psilocybin, LSD and DMT are currently federally illegal Schedule 1 substances, the FDA is currently overseeing Phase I, II and III studies exploring the potential therapeutic benefit of these drugs. Members of the Husch Blackwell psychedelic law team are closely following this progress and concurrent proposed state legislation in multiple jurisdictions, and are positioned to help clients navigate what will no doubt be highly complex and novel legal issues.
