Kolla and inhalant addiction symptoms and signs of use

Reviewed by: Dr. Mahmoud El-Sawy Last updated: September 28, 2026 9-minute read
The short answer

The clearest signs of kolla (glue and solvent sniffing) and other inhalant use are a chemical smell on the breath or clothes, paint or glue stains on the hands, face, or clothing, and a rash or sores around the nose and mouth, along with red eyes and a runny nose. While under the influence, the person looks dizzy, slurs their words, and is unsteady, and with repeated use irritability, falling grades, loss of appetite, and withdrawal appear.

  • The signs can be mild and brief, because the effect wears off within minutes.
  • Do not panic your child or chase them if you catch them under the influence.
  • Loss of consciousness, difficulty breathing, or chest pain call for an ambulance (123).

What are the physical signs of inhaling kolla?

Because the effect is so brief, the clearest signs are the traces the substances leave on the body and clothing:

  • A sharp chemical smell on the breath, clothes, or in the room, like paint or solvents.
  • Paint or glue stains on the fingers, face, or sleeves.
  • Rash, sores, or redness around the nose and mouth.
  • Red, watery eyes, and a runny nose or frequent nosebleeds.
  • Frequent coughing and throat irritation.
  • Loss of appetite, weight loss over time, and a pale face.

What does a person look like under the influence of inhalants?

The effect of inhalants resembles alcohol intoxication, but it starts quickly and wears off within minutes, and it may be repeated several times in a short period:

Movement

Dizziness, staggering, unsteadiness, and slowed reactions.

Speech

Slurred speech that runs together or is hard to understand.

Consciousness

A vacant stare, confusion, and drowsiness, and hallucinations may appear.

The body

Nausea, vomiting, headache, and a rapid pulse.

What are the behavioral and school signs?

With repeated use, changes in behavior and schoolwork appear, which may be the first thing a parent or teacher notices:

  • Irritability, mood swings, and flaring up over small things.
  • A sudden drop in grades, poor concentration and memory, and skipping school.
  • Withdrawing from the family and spending long periods outside the home or in an enclosed space.
  • New friends who are older or unknown to the family.
  • Neglecting personal hygiene and appearance.
  • Frequent lying and hiding personal belongings.

What clues might you find at home?

  • Unexplained shortages of household products with a strong smell, or empty containers of them in unusual places.
  • Items hidden in the child's room or bag that give off a chemical smell for no clear reason.
  • A persistent chemical smell in the room with no obvious cause.

A single clue does not necessarily mean substance use; many children use adhesives for school projects. What matters is a cluster of signs together with a clear change in behavior.

Signs that may appear in younger children

Some children start experimenting at a young age, and their signs are sometimes different or milder, so watch for the following:

  • Frequent headaches, nausea, or dizziness with no clear medical cause.
  • A chemical smell on the hands or clothes after coming back from play or school.
  • Unusual sleepiness in the daytime, or spacing out and difficulty paying attention.
  • An unexplained interest in household chemical products, or asking for them with various excuses.
  • A sudden change of friends, or spending long periods in enclosed places away from adults.

These signs can have other causes, but when they keep recurring they deserve attention and a calm conversation, and a visit to the pediatrician if you are in doubt.

When does inhaling become addiction?

Medical diagnostic guides such as the DSM-5 and ICD-11 describe an "inhalant use disorder" when inhaling is repeated and causes clear harm or distress over a year. Its signs, in brief:

  1. Inhaling more often or for longer than intended.
  2. Unsuccessful attempts to stop.
  3. Spending a great deal of time obtaining the substances or recovering from their effects.
  4. Strong cravings to inhale.
  5. Declining performance at school, work, or in responsibilities.
  6. Continuing despite family and social problems.
  7. Giving up important activities.
  8. Inhaling in dangerous situations.
  9. Continuing despite physical or psychological problems caused by inhaling.
  10. Tolerance: needing more to get the same effect.

When the person stops, symptoms such as irritability, sleep disturbance, nausea, and sweating may appear. You can find how to deal with them on the page Kolla and Inhalant Addiction Treatment.

How do you talk to your child if you suspect inhalant use?

  1. Calm down first; anger and panic do not help, and chasing them while they are under the influence is a danger to their heart.
  2. Wait until the effect has completely worn off, and choose a private place and a suitable time.
  3. Start with what you noticed rather than an accusation: "I noticed a chemical smell and stains on your clothes, and I'm worried about you."
  4. Explain simply that these substances can stop the heart even after one use, without exaggerating or trying to frighten them.
  5. Ask what drives them to do it: peer pressure, boredom, sadness, or a problem at school.
  6. Agree on a clear step, such as visiting a doctor or a psychologist, and follow up with them patiently.

The school's role in early detection

Teachers and social workers see the child for many hours every day, and they may notice the smell, the stains, or the drop in schoolwork before the family does. The right approach is calm communication with the family and referring the child to psychological and social support, avoiding public embarrassment in front of classmates or punishment alone, because stigma pushes the child to hide and keeps them away from help.

Danger signs with kolla and inhalants: call ambulance (123) immediately

  • Loss of consciousness, or no response to calling or touch
  • Difficulty breathing, or breathing that is very slow or has stopped
  • Chest pain, or a fast or irregular heartbeat
  • Seizures
  • Vomiting with severe confusion, or pallor and blue lips

Call ambulance (123), move the person into fresh air and remove the source of the fumes, and place them on their side if they are unconscious but breathing. Do not frighten, chase or shout at them, because a sudden emotional shock can cause a fatal heart rhythm disturbance. Stay with them calmly until help arrives.

Frequently asked questions

Frequently asked questions about the symptoms and signs of kolla and inhalant addiction

Ask on WhatsApp
How do I know my son is sniffing kolla?

The clearest signs are a chemical smell on the breath or clothes, glue or paint stains on the hands or face, and a rash around the nose and mouth, along with irritability and falling grades.

What does the rash from kolla look like?

It usually appears as redness, sores, or dry skin around the nose and mouth, and may come with a runny nose and red eyes.

Does the smell of kolla linger?

The chemical smell may stay on the breath for a few hours, and on clothes and in the room for longer, and it is one of the clearest signs.

Does kolla inhalation show up in a drug test?

Standard drug tests usually do not detect inhalants, so doctors rely on the signs, the history, and the examination, and tests may be ordered to assess the effect on the liver, kidneys, and blood.

What should I do if I find my son under the influence of kolla?

Do not panic him or chase him; calmly move him into fresh air and stay with him. Call an ambulance (123) if he loses consciousness, has difficulty breathing, or complains of chest pain or a seizure.

Do the signs differ between boys and girls?

The physical signs are similar, but some girls may hide their use more, or show withdrawal and sadness instead of irritability, so any clear change in behavior deserves attention.

When should I take my child to a doctor?

As soon as you suspect inhalation, even if he seems fine, because some harm to the heart, liver, kidneys, and nerves does not show at first, and a full checkup is needed.

Does punishment stop a child from inhaling?

Punishment alone rarely works and may push the child to hide. It is better to combine clear limits, calm conversation, and specialist support that addresses the causes.
