A recent report from the Hanley Center, in conjunction with the Caron Treament Centers, found that many older Americans are dealing with mental issues, and it is driving some to abuse substances.

Close to 80 percent of those polled who were 48 or older noted that they first used drugs or alcohol before the age of 25, according to the report. However, 40 percent noted that they felt they were substance abusers at some point from that age on. Nine in 10 noted they abused alcohol, while close to half noted abuse of prescription drugs.

"Older adults face a distinct set of challenges as they enter their golden years," said Dr. Barbara Krantz, medical director of Hanley Center. "This transitional period of life is unique and leads to difficulty in dealing with stressful situations, such as an early retirement or financial strains, which in turn may lead to serious anxiety and depression."

Older Americans who are concerned about poor habits and health risks may want to see a doctor for advice. If they don't have a sufficient healthcare plan, it could benefit them to compare what their current policy is with other health insurance quotes.
