It is possible in theory, but it is not advisable. Stopping heroin abruptly can bring muscle spasms, abdominal pain, dramatic blood pressure changes, increased heart rate, tremors and seizures, along with restlessness, hallucinations and delusional thinking, and some of these need medical attention. Cravings are also intense, so relapse often follows within days or even hours. An inpatient medical detox, with supervision throughout, is the recommended route.
Before you go further, a safety note
Opioid tolerance falls quickly after any break in use, which is what makes returning to a previous dose so dangerous. Never use alone. If you think someone may have overdosed, call 999 in the UK or 112 anywhere in Europe straight away and stay with them until help arrives.
If you are dependent on opioids, speak to a doctor before changing or stopping anything.
Many people use heroin and other opioids. However, there may come a time when someone becomes aware of how dangerous these drugs are and recognise the need to stop using them. Some may believe that quitting cold turkey is the best path forward. To quit something 'cold turkey' means to immediately stop taking a substance. Many people believe that this is a path forward from substance use disorder. But it may not be the safest or most sustainable path to recovery, and trying to detox at home may have a variety of dangers.
Can A Person Quit Heroin Cold Turkey?
In theory, it is possible to quit heroin cold turkey. But just because something is possible in theory doesn't mean that it's safe or practical to do so. Quitting cold turkey can come with a variety of drawbacks. One of the biggest concerns of going cold turkey is that a person needs to have a limitless supply of willpower. People who are addicted to a drug are mentally and physically dependent on it to function. So their minds and bodies will crave it when they stop. These cravings will be almost insurmountable, and a person who tries to go cold turkey will invariably give into them and relapse days if not hours after quitting. Beyond the inevitability of relapse, going cold turkey can also come with various other dangers.
Is Quitting Cold Turkey Safe?
No, quitting heroin cold turkey is not safe. Some of the withdrawal symptoms that can come when a person abruptly stops taking heroin can be dangerous. Many opioid withdrawal symptoms will need medical intervention. Some of the withdrawal symptoms that a person may experience when they stop using heroin can include muscle spasms, abdominal pain, dramatic blood pressure changes, increased pain sensitivity, increased heart rate, tremors, and seizures. Beyond these physical symptoms, detoxing from heroin can also cause a person to become restless, emotionally volatile, have hallucinations, and become delusional. These withdrawal symptoms can be life-threatening without medical attention. So going cold turkey isn't advised.
Why Would Someone Choose to Quit Cold Turkey?
There are a few reasons why someone would choose to stop using a drug abruptly despite the dangers. Some people believe that doing so may help them overcome addiction more quickly. They think that if they can get clean immediately, they won't need prolonged inpatient treatment. Some people may also believe that the only thing they need to overcome addiction is willpower. They think that if they have enough willpower, they'll be able to stop using drugs, manage withdrawal symptoms, and live a sober life.
Consequences of Heroin Misuse
Misusing heroin can lead to a variety of detrimental health effects. These effects can include skin infections, collapsed veins, liver and kidney disease, mental health troubles, sexual dysfunction, and an increased risk of becoming infected with HIV or hepatitis due to sharing needles. In severe cases of addiction, heroin misuse can lead to tolerance. This makes it so that the pleasurable effects of the drug are dulled, so users have to take more to get the high that they want. This greatly increases a person's overdose risk. There are also social consequences to misusing illicit drugs like heroin. Friends and family may recognise the signs of addiction and distance themselves. Conversely, heroin users may distance themselves from their loved ones. Legally, people may face consequences for using or possessing heroin without a prescription depending on local laws. For example, heroin is illegal in the United States, but it is legal in Britain with a prescription. The possibility of these effects can often be a compelling factor that motivates many users to stop using heroin cold turkey.
Worried about your heroin use?
Most people wait far longer than they needed to. A short, confidential conversation costs you nothing and will tell you where you actually stand.
Safe Heroin Detox
Cold turkey quitting isn't advisable. What is recommended is an inpatient medical detox programme. Choosing to go to a rehab or detox centre is the safest way to get clean from heroin. In a treatment facility, a person who needs to get clean will be under direct medical supervision. This means that a highly-trained medical team will intervene in the event of severe withdrawal symptoms. Another benefit of being in a specialised facility is that it can provide an easy transition into other facets of heroin addiction treatment.
Heroin Withdrawal Symptoms Management and Timeline
The team at an inpatient detox or rehab facility doesn't just intervene in cases of severe heroin withdrawal. They can also help a person get through mild symptoms. Now, the methods will be different depending on the specific centre's treatment approach, but many will administer medication. Therapy can be used to help people with the mental and emotional aspects of the withdrawal process. In terms of the timeline, symptoms of heroin withdrawal should present around 8 hours after the last use. These symptoms can last anywhere from 3 to 10 days.
Treatment for Heroin Use
Detoxing and managing withdrawal symptoms are only part of helping a person who is dependent on heroin. Further drug and alcohol treatment will involve a variety of approaches. One of the most important parts of treating heroin use is behavioural therapy. These therapies can help a person address the beliefs and thought patterns that lead to drug use. By changing these cognitive distortions, a person can change their behaviour. Behavioural therapy can also help people manage their emotions and tolerate distress. In doing so, they can help someone manage stressful situations without turning to heroin to cope. Speaking of coping, many substance abuse treatments also have mental healthcare because many people use drugs to manage their mental health troubles.

Questions people actually ask
How soon does heroin withdrawal start and how long does it last?
Symptoms should present around 8 hours after the last use, and they can last anywhere from 3 to 10 days. During that window a person may experience both physical symptoms such as muscle spasms, tremors and pain sensitivity, and emotional ones such as restlessness and volatility. In a detox or rehab setting, staff help with mild symptoms as well as intervening in severe ones.
Why do people try to quit cold turkey anyway?
Some believe that stopping immediately will get them through addiction more quickly, and that if they can get clean straight away they will not need prolonged inpatient treatment. Others believe willpower alone is what is needed to stop using, manage withdrawal and stay sober. The difficulty is that dependence is physical as well as mental, so the body and mind crave the drug regardless of intent.
What does a medically supervised heroin detox involve?
In a treatment facility you are under direct medical supervision, so a trained team can intervene if withdrawal becomes severe and can also help with milder symptoms. Approaches vary by centre, but many administer medication, and therapy is used to work through the mental and emotional side of withdrawal. A specialist setting also makes the move into the rest of addiction treatment straightforward.
What are the health risks of continuing to use heroin?
Misuse can lead to skin infections, collapsed veins, liver and kidney disease, mental health difficulties and sexual dysfunction, plus an increased risk of HIV or hepatitis where needles are shared. Tolerance dulls the pleasurable effects, so people take more to get the same high, and that sharply increases overdose risk. There are social and legal consequences too, and relationships often suffer in both directions.
Why is going back to a previous dose after a break so dangerous?
Opioid tolerance falls quickly after any break in use, which is what makes returning to a previous dose so dangerous. The amount that felt manageable before may not be. Do not use alone. If you think someone may have overdosed, call 999 in the UK or 112 anywhere in Europe straight away and stay with them until help arrives. If you are dependent on opioids, speak to a doctor before changing anything.
