Substance use and addiction remain serious public health concerns—not just among adults, but increasingly among young people. As a parent, guardian, or teacher, knowing the early warning signs and the most dangerous substances can make all the difference.

At Mondia Health, we believe that awareness leads to prevention—and support starts with knowing when and how to step in.

7 Substances That Pose the Highest Risk

1. Fentanyl

An extremely potent synthetic opioid—just a small amount can be deadly. Often mixed unknowingly into other street drugs.

2. Heroin

A highly addictive opioid. Overdoses are common, especially when heroin is laced with fentanyl.

3. Methamphetamine (Meth)

A powerful stimulant. Long-term use can cause psychosis, severe weight loss, and organ damage.

4. Cocaine

A fast-acting stimulant that increases the risk of heart attack and stroke—even for first-time users.

5. Synthetic Cannabinoids (e.g., “Spice” or “K2”)

Lab-made drugs that mimic marijuana but can trigger seizures, hallucinations, or sudden death.

6. Alcohol

Despite being legal, alcohol misuse is a major contributor to accidents, overdose, and long-term organ damage.

7. Benzodiazepines (e.g., Xanax, Valium)

Prescription medications that are dangerous when misused—especially when combined with alcohol or opioids.

How to Spot the Signs of Drug Use in Children and Teens

Substance use can start subtly. Here are key warning signs to look out for:

Physical Signs:
– Bloodshot or glassy eyes
– Sudden weight changes
– Frequent nosebleeds or tremors
– Smell of alcohol or chemicals

Behavioural Shifts:
– Loss of interest in school, sports, or hobbies
– Secretive behaviour or lying
– Changes in sleep or energy levels
– Hanging out with new, unfamiliar friends

Emotional & Mental Changes:
– Mood swings or irritability
– Anxiety, depression, or paranoia
– Periods of extreme energy followed by fatigue

Environmental Clues:
– Missing medication or alcohol
– Small baggies, foil, straws, or rolled-up paper
– Wearing long sleeves to hide marks

What Parents and Guardians Can Do

– Start the conversation early: Talk honestly and openly about drugs and choices—at an age-appropriate level.
– Be present and involved: Know who your child’s friends are, what they’re interested in, and how they’re coping.
– Set clear expectations: Discuss boundaries, consequences, and family values around substance use.
– Seek help early: If you’re concerned, speak to your doctor, a counsellor, or reach out to Mondia Health. Early intervention saves lives.
