Awareness of drug and alcohol abuse among teenagers
3. Introduction
Adolescence is a critical period of physical, psychological, and emotional development, marked by heightened vulnerability to risky behaviours. Substance abuse, involving the harmful or hazardous use of psychoactive substances such as alcohol, prescription drugs, and illicit drugs, represents a significant public health challenge globally. In India, the trend of substance initiation during teenage years is a growing concern, with profound implications for the individual, family, and society at large.
The NCERT Class 12 Biology textbook (Human Health and Diseases), explicitly addresses the issue of drug and alcohol abuse, highlighting its impact on health. It details the physiological and neurological effects of substances like opioids, cannabinoids, and alcohol, and discusses the social and mental health consequences, including addiction, withdrawal syndrome, and increased risk of diseases like AIDS and hepatitis. This project Awareness of drug and alcohol abuse among teenagers extends the theoretical knowledge from the textbook into a practical, social survey-based investigation.
Awareness is considered the first line of defence in prevention. However, mere availability of information does not guarantee informed decision-making. This study seeks to bridge the gap between theoretical knowledge disseminated in academic settings and the practical awareness, perceptions, and attitudes held by teenagers themselves. Understanding this landscape is crucial for designing effective, targeted intervention and education programs within school communities.

4. Materials and methods
- Type of Study: Descriptive, cross-sectional survey-based study.
- Study Population: Students of Classes 11 and 12 (Science stream) from three different schools in an urban setting.
- Sample Size: 150 students (50 from each school), selected via stratified random sampling to ensure gender balance.
- Tool for Data Collection: A self-designed, structured, and anonymous questionnaire (Google Forms and printed copies).
- Questionnaire Design: The questionnaire comprised four sections:
- Demographic Data: Age, gender, class.
- Awareness Assessment: Multiple-choice questions on effects of specific substances (alcohol, nicotine, cannabis, opioids), legal aspects, and signs of addiction.
- Source and Influence: Questions on sources of information (school, family, media, peers) and perceived peer/family attitudes.
- Attitude and Perception: Likert-scale statements on risk perception, reasons for abuse, and efficacy of preventive education.
- Procedure: Permissions were obtained from school authorities. Questionnaires were distributed during a free period. Anonymity and confidentiality were assured. The average time for completion was 15 minutes.
- Data Analysis: Data was compiled in Microsoft Excel. Quantitative data was analyzed using descriptive statistics (percentages, mean scores). Qualitative insights from open-ended responses were thematically categorized.

5. Theory and review of literature
5.1. Biological Basis of Addiction
As per NCERT, drugs interact with the body’s neurotransmitters. For example:
- Opioids (e.g., heroin) bind to opioid receptors in the central nervous system and gastrointestinal tract, producing euphoria and depressing vital functions.
- Cannabinoids (e.g., marijuana, Ganja) affect the cardiovascular system and cannabinoid receptors in the brain, altering cognition and motor coordination.
- Alcohol (Ethanol): A depressant that enhances the inhibitory neurotransmitter GABA and inhibits the excitatory neurotransmitter glutamate, leading to slurred speech, impaired judgement, and slow reflexes.
- Nicotine: Stimulates adrenal glands and increases dopamine levels, causing stimulation and addiction.
Repeated use alters the brain’s reward circuitry, leading to tolerance (need for higher doses) and dependence (physical and psychological need).
5.2. Health and Social Consequences
- Physical Health: Liver cirrhosis (alcohol), respiratory failure (opioids), lung cancer (smoking), increased risk of cardiac arrest, and compromised immune system.
- Mental Health: Anxiety, depression, paranoia, and personality disorders.
- Social Consequences: Academic decline, financial loss, social isolation, violent behaviour, and breakdown of family relationships.
- Public Health Threat: Sharing needles leads to spread of HIV/AIDS and Hepatitis B, as emphasized in NCERT.
5.3. Adolescent Vulnerability
The adolescent brain, particularly the prefrontal cortex responsible for decision-making and impulse control, is still developing. This makes teenagers more prone to risk-taking, peer pressure, and susceptibility to addiction. Factors like curiosity, stress, unstable home environment, and easy availability act as catalysts.
5.4. The Role of Awareness and Prevention
Prevention strategies, as outlined in health education, operate at multiple levels:
- Primary Prevention: Aimed at naive individuals to prevent initiation (e.g., school awareness programs).
- Secondary Prevention: Targeted at early users to prevent progression to addiction.
- Tertiary Prevention: Involves rehabilitation and relapse prevention for addicts.
This project Awareness of drug and alcohol abuse among teenagers focuses on evaluating the foundational element—Primary Prevention through awareness.

8. Results and discussions
8.1. Level of Awareness: The data indicates a moderate to high level of basic biological awareness regarding the harmful effects of common substances like alcohol and nicotine, which aligns with their frequent mention in school curricula and media campaigns. However, awareness about specific mental health impacts and the potent addictiveness of substances like cannabis was relatively lower (68%), revealing a potential gap in education where some substances are wrongly perceived as “less harmful.”
8.2. Dominance of Informal Sources: A significant finding is that the Internet and social media (92%) are the primary sources of information, surpassing formal education channels (78%). This underscores both an opportunity and a risk. While digital platforms provide wide access, the information may not always be scientifically accurate or prevention-oriented. The relatively low influence of family (56%) suggests a need for more open communication at home.
8.3. Attitude-Behaviour Gap: Despite a good mean score (3.8/5) on perceiving experimentation as risky, the high score (4.2/5) on peer pressure as a major reason indicates that knowledge does not automatically translate into the ability to resist social influence. The self-reported confidence in refusal (3.9) is promising but must be viewed with caution due to the potential for social desirability bias in responses.
8.4. Critical Gap in Legal Awareness: The poor knowledge of legal consequences (41%) is a serious concern. The deterrent effect of law is minimized if the target population is unaware of its provisions. This highlights a significant omission in current awareness programs, which often focus solely on health.
8.5. Correlation: A positive, though not absolute, correlation was observed. Students who cited school and family as key information sources tended to have slightly higher awareness scores and perceived higher risks associated with substance use.
8.6. Implications for Prevention: The study reinforces the need for a multi-pronged approach:
- School Curriculum Enhancement: Beyond biology textbooks, interactive sessions with health professionals, former addicts, and legal experts.
- Digital Literacy: Guiding students to identify credible online health resources.
- Parental Involvement Workshops: Equipping parents to discuss these issues effectively.
- Peer-Led Education: Training confident students to be peer educators, as they are a trusted source.

9. Conclusion
This investigatory project Awareness of drug and alcohol abuse among teenagers concludes that while teenagers in Classes 11 and 12 possess a foundational awareness of the biological dangers of drug and alcohol abuse, primarily sourced from digital media, there are conspicuous gaps. These include misconceptions about certain drugs, a critical lack of awareness regarding stringent legal ramifications, and a vulnerable gap between knowing the risks and possessing the skills to withstand peer pressure.
The findings affirm that awareness is not a monolithic construct but a spectrum encompassing health, legal, and psychosocial dimensions. Strengthening formal, interactive, and legally-informed education within the school ecosystem, complemented by empowered family dialogue, is essential to translate this awareness into resilient behaviour, thereby safeguarding adolescent health and well-being as envisioned in the NCERT curriculum on human health.
