Strox addiction symptoms and signs of use

Reviewed by: Dr. Mahmoud El-Sawy Last updated: September 28, 2026 10 min read
The short answer

The most noticeable signs of Strox use are red eyes, a racing heart, vomiting, confusion, panic attacks or sudden odd behavior, and sometimes seizures or loss of consciousness. Over the longer term, families notice withdrawal from others, irritability, slipping grades, requests for money and secrecy. What happens after stopping is withdrawal, which has its own page.

  • A single sign is not enough to judge; several signs together over a period are what call for action.
  • A seizure, loss of consciousness or chest pain is an emergency that cannot wait.

Physical signs of Strox use

These signs appear while the drug is active, in the minutes and hours after use, and their severity varies a great deal from one occasion to the next depending on what the packet contains:

  • Red eyes, and sometimes a glazed or fixed stare.
  • A noticeably fast heartbeat and sweating.
  • Nausea and vomiting, and sometimes a pale face.
  • Heavy, sluggish movement or staggering and loss of balance.
  • Slow or disjointed speech, or silence and detachment from the surroundings.
  • Tremor, and in severe cases seizures or loss of consciousness.
  • A strange perfumed or chemical smell on clothes or in the room.

Behavioral signs

With repeated use, behavioral changes begin, and these are often the first thing a family notices:

  • Isolating in the bedroom for long periods and locking the door or phone.
  • Changing the usual friends and going out at odd hours.
  • Asking for money often, with changing excuses, or things going missing from the house.
  • Slipping performance at school or work and frequent absences.
  • Neglecting hygiene and appearance, and disrupted sleeping and eating patterns.
  • Lying, secrecy and sharp defensiveness when asked.

Psychological signs: when should you be concerned?

The psychological effect of Strox may be its clearest sign, and it can appear suddenly:

Panic and anxiety

Sudden intense fear, a feeling that they are going to die, palpitations and shortness of breath.

Confusion and hallucinations

Seeing or hearing things that are not there, or seeming lost and not knowing where they are.

Suspicion and paranoia

Feeling that people are watching them or want to harm them.

Agitation and irritability

Extreme anger or unusual aggression over minor things.

Between episodes of use you may notice irritability, insomnia and mood swings. Symptoms that continue or worsen after stopping are covered on the page about Strox and Voodoo withdrawal symptoms.

How do the signs change as use continues?

Signs of Strox use by stage
StageWhat the family may notice
While under the effectRed eyes, vomiting, a fast pulse, confusion or panic, staggering, and sometimes sudden odd behavior.
Between episodes of useIrritability, insomnia, poor appetite, boredom and restlessness, and an obvious wish to go out or be alone.
After months of useWeight loss, declining school or work performance, a change of friends, debts or missing money, and persistent mood swings.

Watching how this develops over time is more reliable than focusing on a single incident, so it helps if the family jots down what they notice, with approximate dates, before consulting a specialist.

How can you tell Strox use from hashish use?

Some signs may look alike, such as red eyes and increased or decreased appetite, but there are differences that help families and doctors:

Differences between the signs of Strox and hashish use
The signStroxHashish
Onset and duration of effectVery fast and relatively shortSlower and longer
Repeated vomitingCommonLess common with ordinary use
Seizures and loss of consciousnessPossibleVery rare
Severe agitation and violenceMore commonUnusual
Very fast pulse and chest painMore common and more severeUsually a milder increase
SmellPerfumed or chemicalThe familiar cannabis smell
A standard cannabis testOften negativePositive

Things that may point to use

Small bags holding chopped dry herbs that look like sheesha tobacco or bango, colorful packets with odd brand names, rolling papers, or an unfamiliar perfumed smell in the room are all signs worth noticing, without jumping to accusations.

Signs a school or university may notice

The first signs of Strox use in teenagers often appear outside the home, and observations from teachers and supervisors can help the family step in early:

  • A sudden drop in grades or in concentration in class.
  • Sleeping in lectures or frequent absences with no clear reason.
  • Panic attacks, odd behavior or fainting at school or after going out with friends.
  • A sudden change in the circle of friends or withdrawal from activities.

When do signs of use become an emergency?

Some signs cannot wait and are not the time for a conversation. They call for an immediate call to the ambulance on 123: seizures, loss of consciousness, chest pain or severe palpitations, extreme agitation or complete detachment from reality, and a very high body temperature. At these moments, do not think about punishment or blame; think first about saving their life, and tell the paramedics what you believe they took.

When does use become addiction? Diagnostic criteria

Doctors rely on the DSM-5 criteria for substance use disorders, which total eleven criteria over twelve months, including:

  • Using larger amounts or for longer than intended.
  • Failed attempts to cut down or stop.
  • Spending a great deal of time getting the substance or recovering from its effects.
  • A strong, urgent craving to use.
  • Neglecting obligations at school, work or home.
  • Continuing to use despite clear social, health or psychological problems.
  • Tolerance, and symptoms when stopping.
Degrees of substance use disorder by number of criteria met
Number of criteriaLevel
2 to 3Mild
4 to 5Moderate
6 or moreSevere

The final diagnosis is made by a specialist psychiatrist after a comprehensive assessment, which also looks for any co-occurring mental health condition.

How do you talk to someone you suspect is using Strox?

  1. Do not start the conversation while they are under the influence; they may be frightened, confused or aggressive.
  2. Gather your observations calmly, and talk about specific behaviors you have seen rather than making accusations.
  3. Express your concern for their health and safety before anything else.
  4. Listen more than you talk, and do not get drawn into an argument about how “mild” the substance is.
  5. Offer a clear, practical step, such as a confidential consultation or an assessment appointment.
  6. If they refuse, do not end the conversation, and seek specialist family consultation yourself.

Signs of acute Strox poisoning: call an ambulance (123) immediately

  • Convulsions or violent shaking of the whole body
  • Loss of consciousness or great difficulty waking the person
  • Chest pain, a very rapid heartbeat or shortness of breath
  • Severe agitation, violence, or hallucinations and complete detachment from reality
  • A severe rise in body temperature with heavy sweating or hot, dry skin

Call an ambulance on 123 immediately, move dangerous objects away from the person, and do not restrain them by force or put anything in their mouth during a seizure. If they lose consciousness or the seizure ends, place them on their side in the recovery position, stay with them until the paramedics arrive, and tell them what was taken.

Frequently asked questions

Frequently asked questions about Strox addiction signs and symptoms

Didn’t find your answer?

Ask an advisor directly. The reply is confidential and carries no commitment.

Ask on WhatsApp
How do I know if my son is using Strox?

Look for several signs together: red eyes, bouts of vomiting, panic or sudden odd behavior, along with isolation, repeated requests for money and slipping grades. If you suspect it, seek specialist advice before confronting him.

Are the eyes of someone who uses Strox red?

Red eyes are common, but on their own they are not enough to judge, because they also happen with hashish, allergies and lack of sleep. What matters most is a combination of signs.

How long do the effects of Strox last?

The effect starts quickly and is relatively short compared with hashish, but severe effects such as psychosis or kidney injury may last longer and need treatment.

Why does someone who uses Strox lose consciousness?

Strox can cause extreme drowsiness or seizures that lead to loss of consciousness. This is an emergency: call the ambulance on 123 and place them on their side.

Does Strox smell like hashish?

Usually not; many products have a perfumed or chemical scent added that differs from the smell of cannabis.

Is fainting after using Strox dangerous?

Yes. Any loss of consciousness after use is an emergency, because it may be caused by a seizure or a heart rhythm disturbance. Call the ambulance on 123 and do not leave them alone.

Should I confront my son if I find Strox on him?

Yes, but at a calm time after the effects have worn off, and in a worried rather than accusing manner. It helps to consult a specialist before you talk.
