In older adults, what makes substance abuse particularly critical?

Substance abuse in older adults is particularly critical due to the lower tolerance these individuals typically have to various substances. As people age, their bodies undergo physiological changes that can affect how substances are metabolized and processed. This diminished tolerance can lead to increased sensitivity to drugs and alcohol, resulting in a higher risk of adverse effects, addiction, and overdose.

In older adults, the potential for polypharmacy—taking multiple medications—further complicates the issue, as interactions between substances can lead to serious health consequences. The decline in organ function, such as liver and kidney deterioration, also contributes to the lowered ability to handle substances safely, making substance abuse a significant concern in this demographic.

Other factors, such as increased social support or better access to healthcare, generally work to mitigate risks associated with substance use, rather than enhance them. Additionally, while higher rates of substance experimentation may occur in other age groups, older adults often have a different relationship with substance use, often characterized by misuse rather than experimentation. Therefore, the unique challenge posed by lower tolerance is a critical element in understanding substance abuse in older populations.
