Overview

Cannabis (marijuana) addiction, also known as cannabis use disorder (CUD), is a substance use disorder caused by long-term continuous cannabis overuse. Albeit more benign than other substance dependencies, effective delivery with increased strength and usage can still substantially impact your daily functioning and well-being.¹ 

It is important to explore the root cause of dependency and delve into the psychological, emotional, and behavioural aspects of addiction for the development of adaptive coping strategies. Psychotherapies offer a structured and supportive environment for those struggling with cannabis use towards stress and craving management and building resilience upon relapses. 

Despite emphasising psychotherapies’ effectiveness in long-term cannabis addiction recovery, this exploration will mark the necessity of a holistic approach, taking the complex interplay of substance use and mental health among promoting recovery into consideration. 

What is cannabis addiction?

Cannabis addiction is the compulsive cannabis use despite negative consequences. It occurs because cannabis has disrupted our brain’s reward system that releases dopamine, a neurotransmitter responsible for pleasure and reward.^2,3,4 Prolonged cannabis use (specifically Tetrahydrocannabinol (THC) intake) can alter our brain chemistry, inducing tolerance, dependence, and withdrawal symptoms once intake is reduced or ceased. 

Genetic vulnerabilities, environmental factors, early exposure to cannabis, co-occurring mental health conditions, and societal influences could all contribute to cannabis addiction. Moreover, those with either family histories of addiction or mental health conditions are also at higher risk.² 

Long-term cannabis smoking may harm our lungs and brains, causing respiratory issues, confusion, hallucination, delusions, and potentially impaired coordination and judgement that promote accidents. Developing brains of youths are further susceptible to THC-induced damage, leaving lasting cognitive effects.

The dual diagnosis, like depression, anxiety, and psychosis among half of the cannabis-addicted population, could also be exacerbated, with a higher risk of schizophrenia evolving among adolescents. The resulting sudden mood and behavioural changes can seriously impair daily functioning in social, career, and even self-care aspects.^2,5,6

Types of psychotherapies for cannabis addiction 

Due to the limitations of traditional pharmacotherapies in addressing the psychological, emotional, and behavioural factors that contribute to and sustain cannabis addiction, certain psychotherapies are also used to manage cannabis addiction. These are:

Cognitive behavioural therapy (CBT) 

Cognitive behavioural therapy (CBT) is a goal-oriented talk therapy that addresses the interrelationship between maladaptive thoughts, feelings, and behaviours towards substance overuse. With cognitive and behavioural integration, CBT favours labelling and confrontation of distorted thinking patterns upon substance use, cravings, and coping mechanisms. This approach is through trigger-coping establishments that empower individuals to recognise and substitute their cannabis use-related problematic behaviours. Individuals with improved self-control, adaptive problem-solving and decision-making abilities can thus have deeper insight into the driving factors of their addictive behaviours. Hence, resilience is built to prevent relapses, facilitating long-term recovery.^7,8,9,10 

Contingency management 

Contingency management (CM) is a reward-based approach to boost positive behaviours while discouraging negative ones. By providing tangible rewards, such as vouchers, prizes, or privileges, or withholding negative consequences, CM creates a direct behavioural intervention either between the desired therapeutic cessation of cannabis intake and immediate reward or withholding with negative consequences, owing to the failure of therapeutic goal attainment. 

Through motivational incentives and stimulation to healthier choices, CM has long been convincing upon substance use management. With repetitive positive reinforcement, individuals are encouraged towards cannabis sobriety, treatment engagement, and commitment towards long-term recovery.^11,12 However, the practical provision of tangible benefits would become a concern that needs to be cautious and aware of. 

Motivational interviewing (MI) and motivational enhancement therapy (MET)

Motivational interviewing (MI) and motivational enhancement therapy (MET), targeting intrinsic motivation enhancement for behavioural changes, have been crucial in cannabis addiction management. While MI is a collaborative, client-centred exploration and resolution of change-related ambivalence, MET is an MI-based structured intervention that specifically boosts motivation for change. 

Regarding cannabis addiction, both MI and MET are applied to facilitate clients’ underlying craving exploration, behavioural reasoning, and goal-setting towards addictive behavioural change. Upon change-related uncertainties, resolution and self-efficacy are built within an empathetic, non-judgemental environment. Clients are empowered to take ownership towards sustainable cannabis consumption habit changes with increased therapeutic readiness, engagement, and commitment.^7,13,14,15

Dialectical behaviour therapy (DBT) 

Dialectical behaviour therapy (DBT) is a structured therapy based on CBT. Its combination of cognitive behavioural components and mindfulness practices facilitates the development of mindfulness, distress tolerance, emotional regulation, and interpersonal effectiveness core skills that are particularly instrumental in managing substance use complications. 

DBT reduces the emotional distress associated with cannabis addiction through trigger identification, craving management, and adaptive coping. Individuals could then overcome cannabis cravings through alleviated stress with enhanced self-awareness, emotional control, and improved relationships. Further, it encourages appropriate emotional regulation for long-term cannabis abstinence and addiction recovery.^16,17

Family therapy 

Family therapy, involving the entire family unit, is essential in cannabis addiction recovery treatment with a specialised focus and recognition of family dynamics, communication patterns, and relationships that may contribute to or affect addictive behaviours. 

The unique effect of cannabis addiction can be explored among each family member and, simultaneously, the family as a whole to deepen mutual respect, understanding, empathy, and support. It also guides the identification and addresses the addiction-enabling behaviours, improves communication skills, while enhancing relationships among family members. 

Hence, reinforcing a comprehensive, supportive network for the cannabis addiction population towards improved craving control.^18,19,20

Group therapy and support groups 

Group therapy can be significant in cannabis addiction management by providing a supportive peer connection with similar challenges. While participants can share their experience, insights, and coping strategies freely among fellows. A sense of community and mutual understanding is built to foster maladaptive behaviour identification. The safe and supportive space cultivated could further benefit individuals’ social learning, readiness to receive feedback, encouragement, and practical tips for self-reflection and personal growth. Through empathetic peer support, individuals can have improved social skills, emotional resilience, and a sense of companionship with strengthened support networks to combat feelings of isolation and loneliness that favour long-term cannabis addiction recovery.^21,22

Integrative approaches and holistic therapies 

Despite conventional pharmacotherapies and psychotherapies, an integrated, holistic therapeutic approach with a comprehensive framework that concerns multiple interconnected levels of physical, mental, emotional, and social wellness could further promote cannabis addiction management by viewing them as a whole person. 

Mindfulness practices for relapse prevention 

Despite integration with DBT, mindfulness interventions themselves have been crucial in preventing addiction relapse through cultivating self-awareness, emotion regulation, and coping skills. By non-judgementally staying in the present moment through techniques like urge surfing, mindful breathing and meditation, cognitive control can be promoted to observe cravings despite impulsive reactions. With reward being restructured by enhancing hedonic experiences and positive emotions, mindfulness practices could be extensively integrated into various daily activities such as eating, drinking, cooking, and even bathing.²³ This could enable conscious decision-making with reduced stress reactivity when navigating through adversities, preventing a turn to cannabis.

Holistic therapies integration 

Here, alternative therapies such as yoga, acupuncture, art or music therapy, and nutrition counselling are integrated into cannabis addiction treatment.^{24,25,26,27,28} While adequate exercise, nutrition, and emotional care promote overall balance and holistic wellness, mindful participation can further redirect one’s focus and attention away from cannabis towards the present moment. Hence, improving daily activity engagement and commitment for long-term abstinence for a better treatment outcome.²³

Challenges and considerations 

Despite effectiveness, psychotherapy in treating cannabis addiction may still face unique challenges and considerations impacting its possible outcome. 

Stigma with seeking help 

Due to the less harmful perception of cannabis addiction when compared to other substance dependencies, such as heroin or cocaine, there is an underestimated need for formal treatment and therapies that may reduce motivation and readiness for proactive help-seeking. Overcoming this stigma through public education and awareness of the addictive potential of cannabis is crucial to foster therapeutic engagement and commitment. 

Cannabis use-associated cognitive impairment 

Cognitive deficits resulting from prolonged cannabis use that affect memory, executive functioning, mood, and motivation can impede active psychotherapeutic session participation. Psychotherapists will have to adapt their therapeutic approaches in accommodating the various cognitive circumstances to promote an active participation for optimised treatment outcomes.

Co-occuring mental illnesses 

A comprehensive understanding of clients' mental health and medical history is essential prior to therapeutic approach selection. Individuals often experience mental recovery-hindering comorbid mental health conditions such as anxiety, depression, PTSD or OCD alongside cannabis addiction.^2,29 

Legal and societal factors 

Due to the ever-changing cannabis-related legal constraints and societal attitudes, potentially complicating the discussions and strategies used in therapies, therapists will need to stay informed and updated on relevant laws, regulations, and societal concerns regarding the offerings of safe and effective treatments. 

Summary 

Despite the limited medications discovered, comprehensive psychotherapies, taking individuals’ physical, mental, emotional, social, and behavioural wellness into consideration, have been another crucial component in cannabis addiction treatment. The aforementioned psychotherapeutic approaches, though each with a unique focus and emphasis, could collectively empower individuals across craving management, root cause addressing, and developing appropriate coping mechanisms to maximise cannabis abstinence rate. With further pharmacological discoveries and cooperation in the pharmacotherapeutic and psychotherapeutic fields, more balanced and holistic care among cannabis addicts can be facilitated to sustain long-term recovery, hence enhancing the quality of life and well-being for those affected.
