StartingYoung Insight into adolescent addiction comes as new guidelines urge early prevention

Treatment providers have known for years that adolescents are more susceptible to drug use and consequently, addiction. But now they might know why. Researchers recently discovered a specific pathway in the brain that makes adolescents more prone to problematic substance use, which could lead to stronger prevention efforts. By studying how cocaine affected the behavior of young and adult mice differently, researchers found that a mechanism in the brain which regulates specific protein production also controls addictive behaviors. By manipulating that mechanism, researchers were able to mitigate cocaine’s addictive effects. “Now we have a bidirectional switch that can turn on and off the cocaine-induced changes in the brain,” says lead researcher Dr. Mauro Costa-Mattioli of the Baylor College of Medicine.

“ The excitement of this study is that now perhaps we have a signalling pathway that could be targeted for the treatment of addiction. ”

One size fits all What’s most exciting about the study is that the pathway does not appear to be specific to cocaine. A second study examining nicotine returned similar results, leading researchers to believe any treatments targeting the pathway would be effective for all substances. “In the case of nicotine, it’s exactly the same thing,” Dr. Costa-Mattioli says. “All the drugs of abuse, they reduce the activity, they hijack or change this mechanism.” Researchers say they’re still interested to see if the mechanism plays a role in the transition from social substance use to more problematic use. But they say simply identifying such a crucial link of the substance use chain could lead to significant prevention methods. “Of course, the excitement of this study is that now perhaps we have a signalling pathway that could be targeted for the treatment of addiction,” Dr. Costa-Mattioli says.
