Signs of Marijuana Use in Teenagers:

Marijuana use among teenagers can have detrimental effects on their physical and mental well-being. Identifying the signs of marijuana use is crucial for early intervention and support. 

Here are some common signs that may indicate marijuana use in teenagers:

Behavioral Changes

Adolescents who use marijuana often exhibit significant changes in their behavior. They may become more withdrawn, exhibit mood swings, or show a lack of motivation toward school or other activities they once enjoyed.

Red Eyes

Bloodshot or red eyes are a classic sign of marijuana use. When a person consumes marijuana, it can cause blood vessels in the eyes to expand, resulting in a noticeable redness.

Unusual Odor

The distinctive smell of marijuana is hard to miss. If you notice a persistent smell resembling burnt rope or skunk around your teenager, it could be a sign of marijuana use.

Changes in Friendships

Pay attention to changes in your teenager’s social circle. Sudden changes in friendships, associating with new peers who exhibit risky behaviors, or distancing themselves from long-term friends may indicate involvement with drugs like marijuana.

Poor Academic Performance

Marijuana use can impact cognitive function and memory, leading to a decline in academic performance. If your teenager’s grades begin to plummet or they show a lack of interest in their studies, it might be worth investigating further.

Changes in Appetite

Marijuana can affect one’s appetite, leading to increased food cravings or a sudden loss of appetite. If you notice unusual eating patterns in your teenager, it could be a sign of marijuana use.

Lack of Personal Hygiene

Marijuana use may contribute to a decline in personal hygiene. If your teenager shows a sudden lack of interest in grooming or neglects basic hygiene practices, it could be a red flag.


Keep an eye out for marijuana-related paraphernalia such as rolling papers, pipes, or small plastic baggies. The presence of these items in your teenager’s possession may indicate marijuana use.

Physical Coordination Issues

Marijuana can impair motor skills and coordination. If you observe your teenager having difficulty with balance or coordination, it could be a sign of marijuana use.

Altered Sleep Patterns

Marijuana use can disrupt sleep patterns. Look for signs of excessive sleepiness during the day or insomnia during the night, as these may be indicators of marijuana use.

Secretive Behavior

Adolescents experimenting with marijuana often become more secretive. They may isolate themselves in their rooms, lock doors, or avoid conversations about their activities. Such behavior should raise concern.

Financial Changes

Marijuana use can be an expensive habit. If you notice your teenager frequently asking for money without a reasonable explanation or if the money goes missing from your wallet, it could be related to funding their marijuana use.

Changes in Appearance

Keep an eye out for changes in your teenager’s physical appearance. Sudden weight loss or gain, bloodshot eyes, and a disheveled appearance may suggest marijuana use.

Decreased Motivation

Marijuana can lead to a lack of motivation or ambition. If your teenager once displayed drive and enthusiasm but suddenly seems disinterested or apathetic towards their goals, it could be a sign of marijuana use.

Deceptive Behavior

Teens using marijuana may resort to deception to cover up their actions. They may lie about their whereabouts, provide inconsistent explanations, or become defensive when questioned about their activities.

Unusual Artifacts

Look for peculiar items or artifacts in your teenager’s possession, such as homemade smoking devices, rolling papers, or marijuana-themed clothing. These items may suggest involvement with marijuana.

Emotional Instability

Marijuana use can contribute to emotional instability, resulting in rapid mood swings, irritability, or increased anxiety and paranoia. If your teenager exhibits these emotional changes, it’s important to address the underlying cause.

Decreased Interest in Hobbies

Pay attention if your teenager suddenly loses interest in activities they previously enjoyed. A decline in participation in sports, clubs, or hobbies could indicate marijuana use.

Poor Decision-Making

Marijuana use can impair judgment and decision-making abilities. If your teenager starts making impulsive or risky choices without considering the consequences, it may be a sign of marijuana use.

Change in Speech Patterns

Marijuana use can affect speech patterns, causing slurred speech, difficulty articulating thoughts, or a slower pace of conversation. If you notice significant changes in your teenager’s speech, it’s worth investigating further.

Decreased School Attendance

Marijuana use can lead to a decline in school attendance. If your teenager is frequently absent from school or has unexplained absences, it may be related to marijuana use.

Withdrawal from Family

Adolescents using marijuana may withdraw from family interactions. They may isolate themselves in their rooms, avoid family gatherings, or display hostility towards family members.

Loss of Interest in Future Goals

Marijuana use can diminish one’s aspirations for the future. If your teenager loses interest in pursuing their dreams, college plans, or long-term goals, it could be a consequence of marijuana use.

Increased Sensitivity to Music and Art

Marijuana can heighten sensory experiences, leading to an increased interest in music and art. If your teenager develops an intense fascination with music or starts exploring new art forms, it might be worth considering their involvement with marijuana.

Deteriorating Relationships

Marijuana use can strain relationships with friends, family, and romantic partners. If your teenager’s relationships deteriorate or they become involved with individuals who encourage drug use, it could be a result of marijuana use.

How to React if your teenager is Under Marijuana Addiction?

If your teenager is struggling with marijuana addiction, it’s crucial to approach the situation with care, support, and a focus on their well-being. 

Here are some steps you can take to react effectively:

  8. Foster a supportive environment: Create a supportive and substance-free environment at home. Remove any marijuana or drug-related paraphernalia from the house. Encourage family members to be understanding and supportive throughout the recovery process.
  9. Take care of yourself: Caring for a teenager struggling with addiction can be emotionally and physically draining. Remember to prioritize self-care, seek support from friends, family, or support groups, and consider counseling or therapy for yourself.
  10. Stay persistent and patient: Recovery from addiction takes time and may involve setbacks. Stay persistent, remain patient, and continue supporting your teenager through their journey. Celebrate their progress and encourage them to learn from any setbacks they experience.

Remember, addiction is a complex issue, and professional guidance can be invaluable. Seek the help of addiction specialists or healthcare professionals who can provide personalized advice and treatment options based on your teenager’s specific situation.
