Strox and Voodoo (Synthetic Cannabinoids): Effects, Risks and Treatment
ByEl Massar Center medical team
Published:
Strox and Voodoo are not natural cannabis but herbs sprayed with synthetic chemicals of unknown strength, so they can cause psychosis, seizures and a racing heart from the first uses. Treatment means medical assessment, supervised detox, care for any psychosis, then a behavioural program with aftercare.
What are Strox and Voodoo?
Strox and Voodoo are the street names used in Egypt for a family of substances known medically as synthetic cannabinoids. They are chemicals produced in unlicensed laboratories, sprayed onto worthless dried herbs and sold in small packets as a “natural alternative to hashish”. In reality they have nothing to do with the cannabis plant. What enters the body is a synthetic compound that binds to the brain's cannabinoid receptors far more strongly than hashish does, in some cases dozens of times more strongly.
The bigger problem is that the dose is unknown. One packet may contain a small amount of active chemical and the next a toxic one, even under the same name. Other substances are sometimes mixed in, including pesticides, veterinary sedatives or opioid painkillers, so the effect is unpredictable even for a regular user.
Why Strox is more dangerous than hashish
Many users believe Strox is “milder” because it is cheap and does not show up on routine drug tests. That belief is dangerous. The difference between hashish and synthetic cannabinoids is not a matter of degree but of kind, and the risks show up in several ways:
Acute psychosis: hearing voices, seeing things, paranoid ideas and a loss of contact with reality that can last days or weeks after stopping.
Seizures: including in people who have never had epilepsy.
Severe agitation and violence: sudden rage and impulsive behaviour that endangers the user and those around them.
Fast heart rate and high blood pressure: with chest pain and heart-rhythm problems reported in otherwise healthy young men.
Persistent vomiting and acute kidney injury: caused by dehydration and the direct toxic effect on the kidneys.
Altered consciousness: from heavy drowsiness to coma in severe cases.
Signs of Strox use that families notice
Because Strox is usually smoked like hashish, some signs overlap, but there are features that set it apart. Families typically notice:
Red eyes with a vacant, glassy stare that lasts longer than usual.
Sharp mood swings: hysterical laughter followed by sudden anxiety or panic.
Disconnected speech, or talk about voices and things nobody else can see.
Repeated bouts of vomiting with no clear physical cause.
Weight loss, neglected hygiene and sleeping at odd hours.
Small shiny packets or dried herbs with a sharp chemical smell.
Withdrawal from the family, a new circle of friends and repeated requests for money.
Many of these signs overlap with other substances. Our guide to the symptoms of shabu use is useful for comparison, but the most important step is to have the person seen by a specialist rather than guessing.
Strox and Voodoo withdrawal symptoms
Contrary to popular belief, Strox causes real dependence. Withdrawal symptoms begin within hours to a day after the last dose, peak on the second and third day, and ease over one to two weeks, although poor sleep and cravings can last longer. The most common symptoms are:
Anxiety, tension and irritability.
Insomnia and nightmares.
Strong cravings to use again.
Loss of appetite, nausea and sometimes repeated vomiting.
Sweating, tremor and a fast heartbeat.
Low mood and dark thoughts in some people.
In a proportion of cases psychosis persists, or hallucinations return after stopping. Whether that is “withdrawal” or a mental illness that needs treatment in its own right is a medical question for a psychiatrist, not the family. This is why assessing for dual diagnosis is a core part of evaluating anyone who uses Strox.
Why Strox does not show on a routine drug test
Rapid test strips and routine urine screens look for the breakdown products of THC, the active compound in natural cannabis. Synthetic cannabinoids have a different chemical structure that changes from batch to batch, so the result can be negative despite heavy use. Detecting them requires specialised techniques such as chromatography, which are available in El Massar Center's Laboratory and Testing Unit. Even then, a negative result does not rule out use when the clinical picture is clear.
How Strox addiction is treated at El Massar Center
There is no “antidote” to Strox, but there is a clear, well-tested treatment path. At El Massar Center a patient moves through the following stages, each adjusted to the severity of symptoms, the person's age and their mental state:
1. Full medical and psychiatric assessment
A complete physical examination, blood tests for the liver, kidneys and heart, and a mental-state assessment to identify psychosis, depression or anxiety, as well as any other substances being used alongside Strox, which is very common.
2. Stabilisation and emergency care
If the patient arrives agitated, seizing or dehydrated, the priority is to stabilise vital signs, replace fluids and control agitation with medication under continuous medical supervision, before any talk of a treatment program.
3. Medically supervised detox
Withdrawal is managed in the Detox Program with medication for anxiety, insomnia and nausea and round-the-clock monitoring. The aim is to get the patient through this stage safely and with as little distress as possible.
4. Treating psychotic and psychiatric symptoms
If hallucinations or paranoid thoughts persist, the psychiatrist sets out a plan of medication and psychotherapy that is reviewed regularly, and decides whether the psychosis was caused by the drug alone or has uncovered an underlying disorder that needs longer follow-up.
5. Behavioural rehabilitation
This is where real treatment begins: individual and group therapy based on cognitive behavioural therapy to learn how to handle triggers and stress, and structured options such as the 28-Day Program or Inpatient Rehabilitation for people who need a residential, trigger-free environment.
6. Aftercare and relapse prevention
Because Strox is cheap and easy to find, the risk of relapse is high in the first months, so aftercare, with follow-up sessions, periodic drug screening and support groups, is an essential part of the plan.
How long does treatment take?
Detox usually takes one to two weeks, behavioural rehabilitation one to three months depending on the case, and aftercare continues for at least a year. The timeline is longer when psychosis persists, when other substances are involved or when there is a co-occurring mental illness, and shorter when treatment starts early and the family takes part.
The family's role: what to do and what to avoid
Do: talk calmly at a time when the person is not under the influence, and focus on your concern for them rather than blame.
Do: get professional advice before a confrontation. Our Family Counselling Service helps you plan the conversation and, if needed, an intervention.
Avoid: threats, locking the person at home or trying to “clean their system” with herbs. Unsupervised withdrawal can be dangerous.
Avoid: assuming that a negative drug test means everything is fine.
Key takeaways
Strox and Voodoo are synthetic chemicals, not natural hashish, and the strength varies from packet to packet.
The most serious complications are psychosis, seizures, heart-rhythm problems and acute kidney injury.
They cause real withdrawal that peaks after two to three days and eases within about two weeks.
Routine drug tests may miss them, so clinical signs matter more than a test strip.
Effective treatment combines supervised detox, psychiatric care, behavioural rehabilitation and aftercare.
Early intervention with the family involved markedly improves the chances of recovery.
Yes. Hashish contains THC at a relatively limited strength, whereas Strox is a synthetic chemical that binds to brain receptors far more strongly and at an unknown dose. That is why psychosis, seizures and kidney failure are reported with Strox and only rarely with hashish. Stopping Strox also produces clearer withdrawal symptoms.
Does Strox show up on a drug test?
Usually not on rapid strips or routine urine screens, because those look for the breakdown products of natural cannabis rather than synthetic compounds. Detecting it needs specialised, more sensitive testing, which is available at El Massar Center's laboratory. Even so, the clinical signs matter more than the test result.
Is Strox-induced psychosis permanent?
In most cases hallucinations and paranoid thoughts clear within days to weeks of stopping and starting treatment. In some people, particularly those with a genetic predisposition or a psychiatric history, Strox can uncover an underlying disorder that needs longer follow-up with a psychiatrist. Early assessment is what tells the two apart.
How long does Strox addiction treatment take?
Detox usually takes one to two weeks, followed by one to three months of behavioural rehabilitation, for example in the 28-Day Program, and at least a year of aftercare. It takes longer when psychosis persists or other substances are involved.
Benzodiazepine sedatives and sleeping pills such as Xanax, Valium and Rivotril cause physical dependence within weeks, even as prescribed. Stopping abruptly can trigger seizures and delirium, so treatment is a gradual, supervised taper plus care for the anxiety or insomnia that started it.
Bipolar disorder is a chronic mood illness in which episodes of mania or hypomania alternate with depression, and it is often misdiagnosed as depression alone. It is not cured outright, but mood stabilisers, psychotherapy and regular sleep control it well, and most patients live stable, productive lives in treatment.
Depression is a medical illness, not weakness or a lack of faith. It is diagnosed when low mood or loss of interest lasts at least two weeks alongside changes in sleep, energy and concentration. It responds well to psychotherapy, medication or both, and the earlier treatment starts, the better the odds of a full recovery.
Gaming disorder means a teenager has lost control over gaming, puts it ahead of school, sleep and relationships, and carries on despite harm for around a year. Falling grades, disrupted sleep and rage when stopped call for an assessment. Treatment is outpatient: CBT, family therapy and care for any underlying condition.
