Cannabis can become difficult to stop when use is regular, heavy or linked with anxiety, sleep, stress or other mental health concerns. Some people use cannabis recreationally at first and later find that they rely on it to cope or relax.

Recovery Scotland is an information and referral support service. We do not provide detox, therapy or clinical treatment directly. We can help you understand support pathways and, where appropriate, discuss providers who may be able to assess your needs.

What Is A Cannabis Detox?

Cannabis detox means reducing or stopping cannabis use while the body and mind adjust to functioning without it. Some people can do this with community support, while others may need structured help if use is heavy, long-term, linked with mental health symptoms or difficult to control.

Cannabis withdrawal is not usually considered as medically dangerous as alcohol or benzodiazepine withdrawal, but symptoms can still be uncomfortable and disruptive. If you are worried about your health, mental health or other substance use, speak with a GP or an appropriate treatment provider.

When Is It Right To Detox?

It may be time to seek support if cannabis use feels difficult to control, affects motivation or relationships, worsens anxiety or low mood, disrupts sleep, or continues despite negative consequences.

A GP, drug service or suitable treatment provider can help assess whether community support, therapy, structured outpatient support or residential treatment may be appropriate.

How Cannabis Detox Support Works

Support should begin with an assessment of cannabis use, mental health, physical health, other substance use and current risks. A provider may discuss withdrawal symptoms, triggers, coping strategies, relapse prevention and aftercare.

Recovery Scotland does not carry out assessments or provide treatment directly. We can help you understand what to ask providers and what types of support may be available.

A Detox Or Treatment Plan May Include:

  • A gradual reduction plan where appropriate
  • Support for sleep, anxiety, irritability and cravings
  • Therapy or counselling
  • Relapse prevention planning
  • Support for co-occurring mental health concerns
  • Peer, family or community support
  • Aftercare planning

The exact plan should be based on assessment by a qualified professional or provider.

Managing Withdrawal Symptoms

Cannabis withdrawal symptoms can vary depending on how long and how heavily someone has used cannabis. Symptoms may include cravings, irritability, sleep problems, anxiety, low mood, appetite changes, headaches, sweating or restlessness.

If symptoms feel unmanageable, if mental health worsens or if other substances are involved, seek professional advice.

Physical symptoms of withdrawal include

  • Headaches
  • Heavy sweating
  • Digestive problems, including stomach aches and nausea
  • Fever or chills
  • Shakes
  • Insomnia

Psychological symptoms may include

  • Irritability
  • Restlessness
  • Anxiety
  • Low mood
  • Fatigue
  • Lack of appetite and weight loss

Some of the psychological symptoms can be explained by a chemical present in cannabis called delta-9-tetrahydrocannabinol (THC). THC affects the chemical balance in your brain creating feelings of relaxation and happiness. Without the drug, it inevitably leads to a change in the chemical balance causing a real feeling of depression.

Hence, a detox programme requires a gradual step-by-step process, rather than a ‘cold turkey’ approach. A tapered approach offers the best possible chance of success and alleviates the severity of withdrawal symptoms.

Meanwhile, other simple changes can help. Drinking plenty of water and eating a healthy diet speeds up the process by which you body expels the toxins related to the drug, which in turn decreases side effects and accelerates the feeling of physical and mental wellbeing

Finding Cannabis Detox Support

Support may be available through GPs, NHS or community drug services, counselling, private providers, peer support, outpatient treatment or structured treatment providers.

Recovery Scotland can help you explore support pathways, but we do not operate a treatment facility or provide clinical care directly. If there is immediate danger or risk of harm, call 999. For urgent non-emergency medical advice in Scotland, contact NHS 24 on 111 or speak with a GP.
