In this episode, Evan H. Hirsch, MD welcomes Troy Roach, a citizen scientist and educator, to discuss the revolutionary use of low-dose nicotine patches in the treatment of Long COVID.

Troy Roach, originally from California and a graduate of Virginia Tech, works as a Medical English teacher for nursing and physiotherapy students at two universities in Madrid, Spain. After being severely debilitated by COVID-19 in March 2020, with his functional capacity reduced to approximately 30 percent, Troy dedicated himself to Long COVID as a citizen scientist.

He joined the Renegade Research community, including Remission Biome, and spearheaded an observational study in 2023 on the use of low-dose nicotine patches for the condition. This study analyzed data from 231 participants, with the results published alongside Dr. Leitzke in 2025. Troy is currently preparing for a longitudinal, IRB-approved follow-up study aimed at further developing evidence-based recovery strategies for Long COVID.

In this episode, you'll learn:

• Why nicotine patches differ from smoking or vaping
• How the cholinergic system and vagus nerve are involved in Long COVID
• What the "toxic five" are and how they relate to recovery
• Safe dosing strategies, brands, and protocols used by thousands
• Why some patients experience "remission events" after just a few doses
• Key risks, detox reactions, and how to prepare the body for nicotine use
