Substance Use & Brain Development
The most powerful organ in the human body, as well as the most affected by substance use, is the brain.
Using drugs at any age can be dangerous, but before a person is 25 the brain is especially vulnerable and much more susceptible to substance use disorders, risky behavior, and irreversible damage due to substances.
In fact, 90% of people who have experienced addiction tried a substance before their 18th birthday.
Drug Facts
Early exposure to nicotine during the transition from child to adult may be harmful, since it may derange the normal course of brain maturation and have lasting consequences for cognitive ability, mental health, and even personality.
Nicotine is harmful to developing brains and its use during adolescence can disrupt the formation of brain circuits that control attention, learning, and susceptibility to addiction.
Nicotine exposure in its many forms can adversely affect adolescents:
- Affects key brain receptors, making young people more susceptible to nicotine addiction.
- Young people who have never smoked previously and began using e-cigarettes are more likely to smoke cigarettes in the future.
- Vaping is significantly associated with higher levels of ADHD symptoms, based on a 2019 study of college students.
- Studies have shown that nicotine can worsen anxiety symptoms and amplify feelings of depression.
- Nicotine use — whether through smoking or vaping — can increase stress levels.

Prescription opioids activate receptors in the brain and decrease its pain signals. This receptor interaction is also associated with a release of dopamine into the brain. This can result in feelings of euphoria, elation, or pleasure. When dopamine is released, other areas of the brain react, creating a memory and associates it with pleasure.
Some potential short-term, neurological effects of opioids include:
- Mood changes.
- Depression.
- Drowsiness.
- Impaired memory, judgment, and attention.
Over the long term, prescription drug abuse will affect the brain in the following ways:
- Tolerance: Higher and more doses will need to be taken to achieve the same effects.
- Drug dependence: Withdrawal symptoms such as depression, insomnia, anxiety, restlessness, and irritability can be unpleasant. The individual may decide to continue taking the drugs to avoid these withdrawal symptoms in an attempt to appear to function ‘normally.’

Protective & Risk Factors
What are protective vs. risk factors? Risk factors increase the likelihood that a youth will be susceptible to use substances, while protective factors decrease this likelihood. While it’s impossible to eliminate all risk factors for every youth, prevention seeks to lower the amount of risk factors and increase the amount of protective factors. Many of these factors are connected and are not limited to just one area of a youth’s life. Take a look at this diagram to understand more about what some risk and protective factors are.

Why Prevention?
When it comes to substance use, there are many ways the community can work to help solve the problem. At EWOH, our primary focus is on youth substance use prevention. But why prevention?
Prevention seeks to assess the root of the problem and formulate strategies that will help reduce substance use now, and in the future. By working to change community norms, systems, and polices, we can help create a safer, healthier Easton.

Easton Data
Easton Surveys
Through collaboration with Easton Public Schools and Old Colony YMCA, Easton Wings of Hope coordinates data collection on core measures to assess health disparities. The Youth Health Survey is conducted every two years for grades 7-12, and a Parent/Caregiver Survey is conducted on the alternate year for parents of Easton students in grades K-12. The core measures assessed include 30-day use (current use), perception of risk, perception of peer disapproval, and perception of parental disapproval.
See reports below.
Making Meaning of the Data
The EWOH staff and Steering Committee work with community partners to examine the data collected on an annual basis to compare to past years and state and national data to make meaning of the results.
