Drug Withdrawal Symptoms: What to Expect in Detox

man having withdrawal symptoms

During detox, you may experience what is known as drug withdrawal. There is no reason to be fearful of this, as it is a normal part of drug and alcohol detox. However, if you are nervous about the experience, it may help to know what happens during withdrawal and what type of physical and psychological symptoms you will be treated for in drug detox.

What Is Drug Withdrawal?

When a person stops using drugs or alcohol after a prolonged period of heavy abuse, he or she will experience uncomfortable or painful physical and psychological effects. These symptoms are referred to as drug withdrawal.1

With extended drug and alcohol use, the human body becomes accustomed to the presence of these substances. If and when they are suddenly removed (ie. the user stops using drugs or drinking alcohol), the body reacts with a wide range of unpleasant symptoms, which will vary based on:

  • The types of drugs/alcohol a person used
  • How long they abused drugs
  • How much was consumed each dose
  • The severity of the addiction

The uncomfortable symptoms of drug withdrawal are often what drive people to relapse because they would rather continue using drugs than deal with the discomfort of withdrawal.

What to Expect During Drug Withdrawal

It’s difficult to predict exactly what your drug withdrawal experience will be like in detox, especially if you are unsure what drugs you have taken. It’s also important to note that every drug is different. Therefore, you may experience varying types of physical and emotional withdrawal symptoms.

The National Institute on Drug Abuse (NIDA) cites several different types of commonly abused drugs.2 Based on these types of substances, here are the withdrawal symptoms you can expect to experience.

Withdrawal Symptoms of Cannabis

This type of drug includes marijuana, ganja, and hashish oil, among others. Cannabis is a very widely abused drug both here in the U.S. and abroad. Drugs like marijuana can be addictive and suddenly discontinuing use may result in withdrawal symptoms. Common withdrawal symptoms of cannabis include3:

  • Irritability
  • Anxiety
  • Depression
  • Restlessness
  • Difficulty sleeping
  • Stomach pain
  • Shakiness
  • Fever
  • Sweating
  • Chills
  • Headache

Withdrawal Symptoms of Depressants

This class of drugs includes substances like barbiturates, alcohol, and benzodiazepines. Drug detox for depressants can potentially be very dangerous, so it is always advised to withdrawal from these substances under medical supervision.4 Common withdrawal symptoms include:

  • Depression
  • Anxiety
  • Difficulty sleeping
  • Nausea and vomiting
  • Headache
  • Irritability
  • Loss of appetite
  • Breathing problems
  • Impaired coordination
  • Shakiness
  • Rapid heart rate
  • Cravings
  • Seizures
  • Hallucinations
  • Stroke
  • Delirium tremens
  • Coma

Withdrawal Symptoms of Hallucinogens

Hallucinogens are drugs that alter your perception of time, space, and reality. Examples include LSD, Ketamine, and PCP. Withdrawal symptoms for this type of drug are widely varied but they may include5:

  • Increased heart rate
  • Tremors
  • Increased blood pressure
  • Muscle aches/stiffness
  • Body temperature fluctuations
  • Seizures
  • Panic attacks
  • Psychosis
  • Severe mood swings

Withdrawal Symptoms of Opioids

Opioid detox can be dangerous if it is not completed under the supervision of a medical team. Opioid drugs include heroin, hydrocodone, fentanyl, methadone, morphine, codeine, and oxycodone, among others. Users may experience symptoms of withdrawal after just a few days of using opioids.6 These symptoms typically include:

  • Anxiety
  • Restlessness
  • Muscle aches
  • Watery eyes and runny nose
  • Sweating
  • Yawning
  • Insomnia
  • Stomach cramps
  • Diarrhea
  • Goosebumps
  • Nausea and vomiting
  • Dilated pupils
  • Rapid heartbeat
  • High blood pressure

Withdrawal Symptoms of New Psychoactive Substances

New psychoactive substances (NPS) is a class of designer man-made drugs that are designed to mimic the effects of other illicit drugs. There are hundreds of these drugs being created in clandestine laboratories and trafficked all over the world, but some common ones in the U.S. include synthetic marijuana and bath salts. Synthetic drug detox can be extremely unpredictable because the ingredients are not always known.7 Symptoms may include:

  • Fatigue
  • Hunger
  • Depression
  • Irritability
  • Agitation
  • Tiredness
  • Insomnia
  • Paranoia
  • Aggression
  • Anxiety
  • Strong cravings

Withdrawal Symptoms of Stimulants

Frequently abused stimulant drugs include cocaine, crack cocaine, methamphetamine, and amphetamine. Abuse of stimulant drugs increases the production of dopamine in the brain, creating a sense of euphoria. Repeated abuse of stimulants can easily cause dependence, tolerance, and addiction, and individuals who are detoxing from stimulants will need to be weaned off the drug(s).8 Withdrawal symptoms commonly include:

  • Irritability
  • Mood swings
  • Depression
  • Insomnia
  • Muscle pain
  • Tremors
  • Hallucinations
  • Delusions
  • Suicidal thoughts and behaviors

As previously stated, it’s important to remember that not every person will experience these exact symptoms. Drug withdrawal is a very individualized experience and it will vary based on a number of personal circumstances.
