Senior citizens, especially Baby Boomers, are increasingly using marijuana for pain management, sleep, and recreation, leading to significant social friction with their neighbors. A recent study indicated that about 10% of seniors in New York use cannabis to "fit in." This surge in use is attributed to Baby Boomers coming of age during the 1960s and 70s, making them more open to cannabis, especially with increased legalization. The "Modern Elder Expo" by cannabis brand Life Is Chill, for example, even includes workshops on rolling joints with catnip, though the company faced pushback on plans to install a pot kiosk in a retirement community.

These disputes often escalate into legal threats and police calls. For instance, Fiorella Terenzi, a 64-year-old astrophysicist, reported her 70-something neighbors for marijuana fumes entering her Miami-area home, despite their claims of using medical marijuana in small amounts. Penelope Livingston, 50, also recounted feeling sick from secondhand smoke from an elderly stroke victim and felt that police dismissed her complaints, treating her as the nuisance. Many complain that their concerns are often overlooked in favor of cannabis advocates, including some doctors.

A notable legal precedent was set in Washington, D.C., when Josefa Ippolito-Shepherd sued her neighbor, Thomas Cackett, over persistent marijuana odors. Cackett, a restaurant manager in his early 70s, used medical marijuana for pain and sleep. The D.C. Superior Court ruled in Ippolito-Shepherd's favor in 2023, barring Cackett from smoking cannabis in his home, a decision upheld by the D.C. Court of Appeals in 2025. This ruling highlights the growing legal challenges arising from increased senior cannabis use and the impact on neighboring residents.
