Cannabis Affects Everyone Differently

Cannabis is not a one-size-fits-all substance. Individual responses vary based on genetics, age, body composition, metabolism, existing health conditions, current medications, prior cannabis experience, and many other factors. What works for one person may not work — or may be harmful — for another.

Particular Risks for Older Adults

Older adults face specific risks from cannabis use that are not adequately addressed by general cannabis information sources:

  • Drug interactions. CBD is a potent inhibitor of multiple CYP450 liver enzymes. THC is a moderate inhibitor. These interactions can raise blood levels of warfarin, statins, benzodiazepines, opioids, antidepressants, tacrolimus, and many other medications — sometimes dangerously. Seniors take an average of five prescription medications.
  • Fall risk. Cannabis can impair balance, coordination, and reaction time. Falls are a leading cause of injury and death among older adults. Combined use of cannabis with benzodiazepines, opioids, or other sedating medications compounds this risk.
  • Cognitive effects. While late-onset cannabis use appears less concerning for long-term cognition than adolescent initiation, acute impairment of memory, attention, and judgment occurs at any age and may be more pronounced in older adults.
  • Cardiovascular risk. THC can cause temporary increases in heart rate and changes in blood pressure. Seniors with cardiovascular disease should discuss these risks with their cardiologist.

Always consult your physician and pharmacist before starting or changing cannabis use, especially if you take prescription medications.

Federal Legal Status

Cannabis remains a Schedule I controlled substance under United States federal law. Possession, use, distribution, and sale of cannabis are federal crimes regardless of state law. While a December 2025 executive order directed rescheduling from Schedule I to Schedule III, this process was not complete as of April 2026.

State laws regarding cannabis — both medical and recreational — differ significantly and change frequently. It is your responsibility to understand and comply with the laws of your jurisdiction. This site does not provide legal advice.
