JOHNSON CITY — As substance abuse continues to be a growing problem in this region and across the nation, many people have been left asking, “How did this problem become so severe, and how can I help find a solution?” Meagan Fisher, director of Magnolia Ridge Alcohol and Drug Treatment in Johnson City, answered the following questions about substance abuse and addiction in this area. What do you think is the most commonly abused substance in this region? “Opiates are the number one thing we see, and when I say opiates, that includes people detoxing from Suboxone and Subutex, because that gets grouped into the opioid diagnosis,” Fisher said.
