Synthetic cannabinoid withdrawal: treating strox and voodoo addiction safely

Strox addiction treatment: can someone stop safely?

Yes. Strox addiction treatment is possible, and stopping safely usually begins with a psychiatric assessment and then synthetic cannabinoid withdrawal under psychiatric medical supervision, where withdrawal symptoms, insomnia, agitation and any psychotic symptoms are treated, followed by a rehabilitation and follow-up program that helps your son not go back. Stopping alone at home after repeated use, whether all at once or by cutting down on his own, can be hard and sometimes dangerous, because these substances are often stronger than hashish and their effects are hard to predict.

The names differ from country to country: strox and voodoo in Egypt and joker in Jordan, known internationally as spice or K2. All belong to one family, "synthetic cannabinoids": lab-made chemicals added to dried plant material. The US National Institute on Drug Abuse (NIDA) links them to severe, potentially life-threatening health problems. To understand the substance itself and its acute symptoms, read our guide to strox and voodoo.

Is strox addictive? FRANK, the UK's drugs information service, explains that research suggests people can become dependent on these substances, especially with regular use. In other words, your son may not keep using because he "doesn't want" to stop, but because his body and brain have got used to it. That is what makes medical treatment sensible, not a punishment.

1. A medical and psychiatric assessment to judge the level of risk and the right kind of care.
2. Safe withdrawal under medical supervision, in hospital or as an outpatient depending on the case.
3. Rehabilitation, psychological and behavioral, including the family.
4. Aftercare and follow-up to prevent relapse.

Strox and spice withdrawal symptoms: what happens after stopping?

A study published in 2022 in the journal Psychopharmacology, based on Global Drug Survey data from 2015 and 2016, included 284 people who had used synthetic cannabinoids more than ten times in the previous year and had tried to stop before. Participants reported more than four withdrawal symptoms on average, most commonly sleep problems (59.2%), irritability (55.6%) and low mood (54.2%). The number of symptoms rose with how often and how much of the substance people used.

Other symptoms mentioned by health sources and medical case reports include:

• Strong cravings and repeatedly thinking about the substance.
• Insomnia and disturbed sleep.
• Irritability and mood swings, anxiety and distress.
• Loss of appetite and weight loss.
• Sweating, tremor, diarrhea and chills.
• Palpitations, chest pain and headache.
• Seizures: rare and described in individual case reports, but a seizure is an emergency: call an ambulance on 123 at once.

There is no fixed timeline that applies to everyone; how severe and how long withdrawal is depends on how long and how heavily the person used, and on their physical and mental health. So don't compare your son with a friend who "stopped on his own"; let a doctor assess his own situation.

Why does strox withdrawal need more medical supervision than hashish?

The active substance in hashish only partly activates the brain's cannabinoid receptors, while synthetic cannabinoids often activate them fully and bind more strongly. In the same international study, participants rated these substances as quicker to act and shorter-lasting, quicker to build tolerance (needing more to get the same effect), and worse in withdrawal than high-potency herbal cannabis: of the 200 participants who picked one of the two on the withdrawal question, 90% said synthetic cannabinoid withdrawal was more severe. The researchers noted that the withdrawal appears more "physical" than cannabis withdrawal, with symptoms such as sweating, palpitations and tremor.

A medical case published in 2022 describes a 44-year-old man who used these substances daily and said he had been using them for about 24 years; when he began cutting down, he had two seizures for the first time in his life, which his doctors considered a possible withdrawal symptom. Such cases are rare in published research, but the doctors who wrote about it warned that withdrawal may include seizures in people who have used daily for long periods. On top of that, as FRANK explains, the strength can vary from pack to pack and batch to batch, so nobody knows exactly what the body has become used to.

The first phase: treating agitation, sleep loss and synthetic cannabis psychosis

In the first days, the goal is for withdrawal to pass safely and for your son to get back his sleep and calm. The researchers behind the international study point out that there is not yet a research-proven medication approach for withdrawal from these substances specifically, so the doctor treats the symptoms themselves: they may decide on sedatives for a short, defined period, or medicines for sleep or anxiety, while monitoring pulse, blood pressure and fluids. Medicines, their doses and how long they are taken are decided by the doctor alone; the family should never give him any medicine of their own.

Psychosis after strox: does it go away?

During or after use, psychotic symptoms may appear, such as morbid suspicion, hallucinations, disorganized speech and agitation. In a systematic review published in 2025 that brought together 35 studies, benzodiazepine sedatives were the first line for calming agitation in most studies, with antipsychotics added when symptoms persisted. Acute symptoms resolved in about 90% of cases within roughly one to four days. But most of this evidence comes from case reports and uncontrolled studies, so the researchers rate its certainty as low to very low.

The same review found that psychosis lasting weeks or months was linked to continuing or returning to use, or to a pre-existing psychotic disorder. It noted that some cases settled with supportive care alone: a calm, low-stimulation environment, verbal de-escalation, enough fluids and close observation. And it stressed that longer-term care needs education, counseling aimed at stopping use and referral to addiction services to reduce relapse. All of this starts in the medically supervised detox phase.

Why is a psychiatric assessment part of treatment, not an extra?

Many young people don't start strox out of nowhere; behind it there may be anxiety, depression, attention difficulties or trauma they have never talked about. The US National Library of Medicine (MedlinePlus) explains that having a mental disorder alongside addiction is called a "dual diagnosis", and that treating both problems together is important.

• Telling a passing substance-induced psychosis apart from an ongoing psychotic disorder, since each needs a different plan and follow-up.
• Treating depression and anxiety, which may surface clearly after stopping and push toward using again if left alone.
• Assessing the risk of self-harm, a routine question in any serious psychiatric assessment.
• Choosing medicines that don't interfere with recovery, a purely medical decision.

That is why treatment begins with an appointment with a psychiatrist, not with withdrawal alone: withdrawal removes the substance from the body, but the assessment explains why it was there in the first place. At Oxygen Center, doctor appointments and therapy sessions are for men and women aged 15 and over (under 18 with a guardian's consent), while inpatient stays such as detox are for males only.

Rehabilitation, the family's role and returning to school or work

Once the body has settled, the part that makes the long-term difference begins. MedlinePlus notes that counseling in addiction treatment can be individual, family or group-based. With strox, research has not yet established a medicine for the addiction itself or for preventing relapse, so education, counseling and ongoing addiction care, which the 2025 review called essential for reducing relapse, are the core of this stage. The doctor may still decide on medicines for particular symptoms such as insomnia or anxiety, or for an accompanying mental disorder such as depression. In our rehabilitation program, your son learns:

• To recognize craving triggers, such as certain friends, places or pressures.
• Alternative skills for coping with boredom, stress and insomnia.
• A written plan for what to do if he is offered the substance or feels weak.

The family's role is not surveillance and searching, but agreeing on clear, calm rules, cutting down on accusations and shouting, and learning a way of talking that encourages honesty. Going back to school, university or work is gradual and planned with the treatment team: when he returns, how he handles old friends, and who he turns to if he feels under pressure.

How long strox addiction treatment takes is not a fixed number; it depends on how heavy the use was, whether there is psychosis or another mental disorder, and how supportive the surroundings are. The doctor sets a rough plan after the assessment and adjusts it as progress is made.

Relapse: why it happens and how aftercare lowers the risk

In a 2020 publication, NIDA explains that relapse rates for substance use disorders range between 40% and 60%, not very different from rates of symptoms returning in chronic illnesses such as high blood pressure and asthma. Relapse does not mean treatment has failed; it is a sign that the plan needs to be resumed or adjusted.

With strox in particular, relapse carries an extra danger: the 2025 systematic review reported that psychotic symptoms returned in everyone who went back to using after recovering from them, among the cases it identified, although, as noted above, its evidence is limited. So the plan does not end when your son leaves hospital. Aftercare within the rehabilitation program continues with follow-up appointments, psychotherapy sessions and support for the family, and with agreed early warning signs such as disturbed sleep, isolation and going back to friends who use.

When to get help immediately, and how to arrange urgent admission

If your son has psychotic symptoms or is unsafe but does not need an ambulance at this moment, call Oxygen Center's 24/7 emergencies line on +20 100 006 6752, or the mobile and WhatsApp number +20 101 687 0711 (or the landline +20 45 320 0011). Explain what is happening, and the team will guide you to the right next step, whether that is coming in for an assessment or admission. You can also call the Ministry of Health and Population's 24/7 mental-health line, 16328, for guidance in a mental-health crisis. In Egypt, the Fund for Drug Control and Treatment of Addiction also runs a 24/7 hotline, 16023, for confidential treatment through its partner centers. Until help arrives:

• Speak calmly in short sentences, and don't argue with strange ideas or suspicions.
• Reduce noise and light, and keep fewer people around him.
• Put sharp objects and medicines out of reach, and don't leave him alone.
• Don't try to restrain him by force yourself; your safety and his come first.
• Gather what you know: what he took and when, and any medicines or past illnesses.

If he talks about death or ending his life, or shows signs such as deep hopelessness or saying goodbye to people, ask him directly and calmly: "Are you thinking about ending your life?" Asking does not plant the idea; it opens the door to talking. Listen without blame and stay with him. If you feel he cannot keep himself safe or is in danger now, call an ambulance on 123 straight away or go to the nearest emergency department. If there is no immediate danger, you can also get support from the mental-health line 16328 or the center's emergencies line +20 100 006 6752, both 24/7; these lines are extra support and do not replace the ambulance when there is danger. If he refuses treatment while stable, see our guide for parents when a son refuses treatment.
