The dangers of cannabis in teenagers

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 parents protect their 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 environment or a permissive social context.

🔹 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.

🔹 Easy 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 in with 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 to 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.

Health and behavioral consequences

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:

• Smoking-related diseases (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 progressive tolerance to THC, the main psychoactive compound of the plant. As the body gets used to the effects, the adolescent may be tempted to increase doses or 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 bearings, 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

✅ Responsibility

• Rather than simply forbidding, show the concrete consequences:
  • “If you use before driving, you could cause an accident.”
  • “Regular use can make you 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 questions:
  • “What do you know about cannabis?”
  • “Have you ever been in a situation where someone offered you to use?”
  • “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.
