Addiction and Essential Oils: Science, Evidence & Practical Insights

Introduction

Addiction touches the lives of millions of individuals and families, often creating emotional, physical, and social challenges along the way. Essential oils are increasingly discussed as supportive tools in addiction and substance use disorder recovery. Several studies exist on how oils such as bergamot, lavender, and black pepper can enhance emotional resilience, help ease withdrawal symptoms, and strengthen coping abilities when used as complementary therapies.

In a previous article, we highlighted a 2025 study suggesting that bergamot essential oil may support substance use disorder (SUD) recovery by enhancing emotional stability and overall well-being. Participants in outpatient treatment who inhaled bergamot oil three times daily for one week reported feeling calmer, with reduced depression, anxiety, and stress.

This article takes a closer look at the current evidence on essential oils in addiction — including animal studies, human trials, and proposed mechanisms of action. This will help you better understand how specific oils may fit into a well-rounded, integrative approach to recovery. Here’s a quick look at what you’ll find in the full article:

Understanding Addiction, Neurobiology, and How Essential Oils Fit

Addiction involves complex changes in brain chemistry, particularly in circuits related to reward, motivation, and craving. Neurotransmitters such as dopamine, GABA, glutamate, opioid peptides, and stress-related signaling molecules play central roles (1, 2, 3, 4,5). Conventional treatments often target these systems through medication and behavioral therapies.

One holistic tool I often use in my naturopathic and functional medicine practice to support my clients’ brain health and behavior is essential oils. Olfaction is a powerful sensory system, with receptors not only in the nose but also in key areas of the central nervous system that influence addiction, motivation, and emotional regulation. Aromatherapy engages these olfactory–limbic pathways, linking scent perception directly to regions that govern emotion, memory, and ultimately, habits.

Both clinical and preclinical studies suggest that inhaling essential oils can reduce anxiety, improve mood, and affect hormones, neurotransmitters, and stress-related biomarkers. For these reasons, aromatherapy may serve as a supportive adjunct to conventional care, helping calm the nervous system for individuals with SUD and addictions (R, R, R).

 

Scientific Studies: Animal Research on Essential Oils for Addiction

Some essential oils are showing promising effects in research related to the brain and addiction.

Dopamine Transport & Essential Oils In studies with animals and cells, certain oils appear to boost the availability of the dopamine transporter (DAT), which helps regulate dopamine signaling. Since dopamine plays a big role in reward and tolerance, these oils might influence those pathways in helpful ways.

Morphine Withdrawal Models Researchers have also looked at how certain essential oils might ease withdrawal symptoms in morphine-dependent animal models, offering clues about their supportive role in recovery:

• Thyme essential oil helped reduce withdrawal symptoms in mice, possibly by interacting with opioid receptors.
• Rose essential oil also showed promise, easing signs of morphine withdrawal through effects on GABA receptors.

While this research is still early, it’s exciting to see how these natural tools might support the nervous system and emotional balance during recovery.

 

Human Research & Clinical Observations

In the 2016 Spring edition of the Journal of the International Federation of Professional Aromatherapists (pp. 21–25), Jane Buckle shared research conducted by her students across the United States exploring how essential oils might support people dealing with different addictions. She also provided a helpful overview of the scientific literature, covering both animal and human studies.

Her students looked at essential oils for nicotine, alcohol, substance, and food-related behaviors, with study sizes ranging from just a few participants to over 170. Certain oils were highlighted for specific uses:

• a blend of juniper, rose, and oris appeared helpful for benzodiazepine withdrawal
• angelica, black pepper, and helichrysum were noted for supporting nicotine dependence.

Buckle’s review of human trials also reported encouraging results:

• Benzodiazepine and nicotine dependence – Protocols similar to those used by Buckle’s students showed positive effects.
• Substance abuse – Oils like ylang ylang and peppermint demonstrated support for opioid withdrawal in small trials.
• Alcohol Abuse– In one study, 99 participants were enrolled to compare aromatherapy with acupuncture for reducing alcohol cravings; 36 completed the trial, and both approaches were equally effective. Another trial found that lavender, Roman chamomile, and ylang ylang helped reduce restlessness during alcohol withdrawal.
• Food cravings – While the concept of food as an “addiction” is still debated, a few small studies have explored the role of essential oils in managing cravings. A 2005 study with 30 women compared two essential oils to a control group: those using mandarin lost an average of 2.4 pounds, lavender users lost 5.3 pounds, and the control group lost 1.2 pounds. In another study with 21 volunteers, fennel oil reduced cravings and slightly boosted weight loss compared with controls (3.51 pounds vs. 2.81 pounds).

While many of these studies are small, they provide intriguing evidence that essential oils may have practical applications in supporting recovery and managing cravings across a variety of addictions.

 

How Aromatherapy May Support SUD and Addiction Recovery

While essential oils are not a cure, they can provide supportive benefits for those in recovery. Some programs incorporate aromatherapy alongside structured therapies, such as CBT (cognitive behavioral therapy), to help enhance focus, calm, and mindfulness. Different oils can also be used to address common symptoms experienced by individuals recovering from SUD or addiction, including:

Mood Imbalances & Stress

Because aromatherapy engages the olfactory system, it can have a direct calming effect on the brain while also influencing physiology and emotions. Essential oils can be used to help regulate the autonomic nervous system, support vagal tone, and balance hormones, helping the body respond to stress more effectively.

Mental Health Disorders

Supporting mental health is especially important because co-occurring mental health conditions are common in people with SUD. When left untreated, these conditions can worsen treatment outcomes, increase functional impairment, and make recovery more challenging. Aromatherapy may offer an additional layer of support.

For example, a 2025 study found that participants in outpatient SUD treatment who inhaled bergamot essential oil three times daily for just one week reported feeling calmer, with reduced symptoms of depression, anxiety, and stress. This suggests that certain essential oils may help complement conventional care by easing emotional strain during recovery.

Relaxation, Sleep, and Withdrawal Symptoms

Essential oils can also support relaxation and sleep—two key components of recovery. For example, lavender and chamomile are often used to reduce anxiety and improve sleep quality, while peppermint and ginger can help ease nausea, support digestive, and enhance focus, which is especially helpful during withdrawal.

When used intentionally, aromatherapy may also address deeper psychological and neurological factors that influence recovery. Potential additional therapeutic benefits include:

• Supporting engagement in therapy
• Reducing emotional intensity
• Building stress resilience
• Improving adherence to broader wellness plans

 

How Aromatherapy May Support SUD and Addiction Recovery & Limitations

In my 20+ years as a naturopathic doctor and certified functional medicine practitioner, I’ve incorporated essential oils into mental health and addiction protocols to complement both integrative and conventional psychiatric care. They can influence:

• Emotional processing
• Physiological stress responses
• Autonomic tone
• Psychological resilience

That said, it’s important to keep a few limitations in mind:

• Most studies are small, preliminary, or anecdotal
• Essential oils are not approved as primary treatments for addiction
• High-quality randomized clinical trials are still lacking
• Effects can vary widely from person to person

In short, essential oils may provide supportive benefits and help complement care, but they should never be considered a standalone treatment for addiction.

 

Safety & Best Practices of Using Essential Oils for Supporting Addiction and SUD Recovery

Essential oils can be a helpful part of recovery, but it’s important to use them safely. Here are some basic guidelines to keep in mind:

• Always use quality oils from reputable sources.
• Diffuse or dilute oils appropriately; avoid ingesting them unless supervised by a qualified professional.
• Consult healthcare providers before use, especially if you have respiratory conditions, skin sensitivity, or are on medications.

 

Taking a Holistic Approach: How Essential Oils Can Support Recovery

Essential oils show real promise as supportive tools within a holistic recovery framework, particularly for managing stress, mood, and overall quality of life. Animal studies suggest potential neurological effects, and there is some human research supporting their use for easing withdrawal symptoms and aiding recovery.

From a naturopathic and functional medicine perspective, essential oils offer a mind-body approach to mental health and addiction recovery. They address both psychological and underlying relational and neurobiological factors.

While they are not a cure for addiction, essential oils can help support emotional balance, stress management, and overall well-being. By complementing conventional and integrative treatments, aromatherapy offers a practical, mind-body tool that can help individuals in recovery feel calmer, more resilient, and better able to engage fully in their healing journey.
