The dangers of cannabis among adolescents: understanding and acting

An alarming reality

Depression, school failure, romantic difficulties, psychosis... the dangers of cannabis among adolescents are a reality. What are the consequences of cannabis use during adolescence? Can we protect our children from this scourge? This article reviews a phenomenon that has persisted for several decades.


Why do adolescents use cannabis?

Adolescence is a transitional period marked by the quest for independence, the need for self-assertion, and the exploration of taboos. This desire to emancipate pushes some young people to experiment with risky behaviors, often under the influence of their surroundings or a permissive social context.

🔹 A minimized perception of dangers: Cannabis is often considered a "soft drug," which can lead adolescents to trivialize its use without measuring the real impacts on their health and cognitive development.

🔹 Easier access and relatively low cost: Unlike other illicit substances, cannabis is more accessible and affordable, which encourages early use.

🔹 Group influence and social pressure: The desire to fit into a group, follow a trend, or avoid being seen as different can lead to initial experimentation.

🔹 Curiosity and the search for sensations: Adolescence being a phase of exploration, some young people are attracted by the euphoric effect of cannabis, sometimes without understanding the long-term consequences.

Although this use is often seen as harmless, it can cause effects on memory, concentration, and psychological well-being, with increased risks of addiction depending on the frequency and intensity of use.


The consequences on health and behavior

Effects on the brain

Cannabis use, especially before the age of 15, disrupts brain maturation. Studies link this drug to serious disorders, such as schizophrenia.

Dangerous behaviors

The psychotropic effects of cannabis increase the risks of:

  • Diseases related to smoking (cancers, cardiovascular disorders).
  • Road accidents.
  • Unprotected sexual intercourse.
  • Violence and impulsive behaviors.


Emotional impact

Depression and suicide are possible consequences among adolescent users. Under the influence of drugs, they may act impulsively, exacerbating preexisting problems.


The risk of addiction and the gateway effect to other drugs

Regular cannabis use leads to a progressive tolerance to THC, the main psychoactive compound in the plant. As the body gets used to the effects, the adolescent may be tempted to increase the doses or to turn to other substances to regain stronger sensations. This phenomenon, known as the gateway effect, can lead to experimenting with more powerful and addictive drugs.

🔹 "Classic" drugs: Some cannabis users end up trying stimulants like cocaine, ecstasy (MDMA), or opiates like heroin, often influenced by their social circle or in search of new sensations.

🔹 New psychoactive substances (NPS): Easier access to synthetic drugs on the Internet has led to the emergence of new powerful and dangerous substances, such as synthetic cannabinoids (Spice, K2), cathinones (m-CAT, Flakka), or synthetic opioids (fentanyl, nitazenes), with effects far more destructive and addictive than cannabis.


Long-term consequences

📉 School dropout

  • Loss of concentration, decreased motivation, and impaired cognitive abilities affect academic performance, increasing the risk of repeating a year or dropping out of school.

🩺 Physical and mental health

  • Risks similar to those of tobacco, including respiratory, cardiovascular disorders, and weakened immune system.
  • Early use can also promote anxiety, depression and, in some cases, trigger latent psychiatric disorders (such as schizophrenia).

🤝 Personal and Social Relationships

  • Excessive use can impair judgment and encourage risky behaviors, including early and unstable relationships, impulsive marriages, or unwanted pregnancies.
  • Family conflicts, loss of guidance, and social isolation are common among young regular users.



1. Strengthen Educational Initiatives

School programs play a key role in raising awareness about the dangers of cannabis and other substances. However, teenagers may resist institutional messages, especially when they come from an authority figure. The approach must be adapted, interactive, and realistic, focusing on concrete testimonies and accessible scientific facts.

2. Adopt Effective Prevention Strategies

Accountability

  • Rather than outright forbidding, show the concrete consequences:
    • “If you use before driving, you could cause an accident.”
    • “Regular use can cause you to lose professional opportunities.”
    • “Your sports and school performance could suffer.”

Open and Non-Judgmental Dialogue

  • Teenagers are more likely to listen if the dialogue is based on active listening and kindness. Rather than demonizing, ask open-ended questions:
    • “What do you know about cannabis?”
    • “Have you ever been in a situation where someone offered you to use it?”
    • “What would make you want to try?”

Inform to Decide Better

  • Rather than fueling fear, explain how drugs affect the brain and their real consequences. A well-informed teenager will be more likely to make informed decisions.

3. Provide access to support resources

📞 Drogues Info Service (0 800 23 13 13 – anonymous and free call)

  • A listening and advice line for young people and their families.
  • Available 7 days a week, with trained professionals to answer questions, reassure, and guide towards appropriate solutions.

💻 Fil Santé Jeunes (www.filsantejeunes.com)

  • Platform dedicated to young people aged 12 to 25 with a chat, forum, and articles about substance use.
  • A pedagogical and caring approach to help young people better understand the risks and set their own limits.

🏥 Young Consumers Consultations (CJC)

  • Available in many cities, these consultations allow young people and their families to benefit from individualized and non-judgmental support.
  • Free and confidential access.

🏫 Interventions in schools and community settings

  • Organizations like France Addictions or la MILDECA (Interministerial Mission for the Fight Against Drugs and Addictive Behaviors) offer prevention actions tailored to young people, based on exchange and awareness.



Conclusion

Cannabis is an ever-present danger that teenagers face. Being vigilant, empowering your children, and maintaining constructive dialogue are essential steps to protect them. Together, we can reduce risks and help young people avoid the pitfalls of cannabis use.
