Cannabis has been used for medicinal purposes for millennia, with the earliest texts documenting its use as far back as approximately 2700 B.C. Only in the late 19th and early 20th centuries did the world begin to prohibit cannabis use. Fortunately, in the last decade there has been a step back in legal restrictions on marijuana and every year more and more countries are decriminalizing both recreational and medicinal use. Among these medicinal uses, cannabis could help in the treatment of eating disorders. In this article we will discuss what eating disorders are and how cannabis can help treat them.

Understanding eating disorders:

Eating disorders are multifaceted conditions involving a complex interaction of biological, psychological and environmental factors. People with eating disorders often experience disturbances in their psychological well-being, eating behavior, and perception of body image. These conditions can have serious physical and mental consequences, affecting an individual's overall quality of life.

Conventional treatment:

Disorders such as anorexia nervosa, bulimia nervosa and binge eating disorder affect a significant number of people worldwide and are still not adequately addressed by society. Conventional treatments for these disorders usually include a combination of therapy, medication and nutritional support; however, the effectiveness of these treatments can vary from case to case and from patient to patient, which has sparked a growing interest in exploring alternative therapeutic options such as cannabis.

The endocannabinoid system:

The endocannabinoid system (ECS) is a complex network of enzymes, receptors and certain chemical compounds called cannabinoids that is present in the human body and plays a crucial role in regulating physiological processes such as appetite, mood, stress, sleep and reward mechanisms. In some cases, people with psychological disorders may have an altered ECS, which could cause dysfunctions in their physiological processes.

Cannabis and its components:

The cannabis plant contains over 100 different chemical compounds, known as cannabinoids. The two main cannabinoids of interest are delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). It is known that these cannabinoids can interact with our endocannabinoid system, sometimes binding to receptors in our brain and skin and helping to regulate certain bodily functions and cellular responses.

Effects of cannabinoids on feeding behavior:

It is known that cannabinoids, especially THC, can modulate appetite and food intake. People who have used cannabis before are familiar with the feeling known as "munchies" that arises after the "high": a sudden appetite and enjoyment for various types (if not any type) of food. THC interacts with CB1 receptors in the reward and appetite centers of the brain, influencing the release of neurotransmitters involved in appetite regulation. This interaction may increase hunger and reduce symptoms of anorexia nervosa.

Clinical studies and observational data:

Because cannabis has been illegal for the past century, clinical research on the use of cannabis to treat eating disorders is limited. Still, some studies confirm that THC can increase appetite and enjoyment of food in patients. In addition, anecdotal evidence suggests that people with eating disorders can use cannabis to relieve anxiety, depression, and body dissatisfaction.

Action potential mechanisms:

The potential therapeutic effects of cannabinoids in eating disorders are believed to be multifaceted. Cannabinoids may influence appetite regulation by modulating brain cell signals and responses in systems involved in hunger. In addition, cannabinoids have been shown to possess anti-inflammatory and neuroprotective properties, which could reduce chronic inflammation and neurobiological alterations associated with eating disorders.

Considerations and safety:

While cannabis shows promise as a potential treatment option for eating disorders, several safety considerations and precautions must be taken into account. Individual responses to cannabinoids may vary and side effects such as cognitive impairment, mood changes and dependence should be carefully monitored. It is also recommended to use the best quality products possible that are properly labeled and show the correct percentages of CBD, THC and other compounds.

Cannabis in Barcelona

There is a thriving cannabis culture here in Barcelona, thanks to the decriminalization of marijuana in Spain and our favorable climate for growing the plant. Thanks to this, people can obtain properly labeled products that come from approved suppliers. If you are considering using cannabis products, make sure you get them from a Barcelona cannabis association or weed club, and not from the street, where it is impossible to know the origin and quality of the marijuana. If you are not yet a member of a cannabis club, all you have to do is apply on their website and wait to receive an invitation.


The use of cannabis in the treatment of eating disorders is a complex and evolving field of research. While clinical and anecdotal evidence suggests potential therapeutic benefits, additional well-designed clinical studies are needed to establish the safety, efficacy, and optimal dosing protocols of cannabinoids for eating disorders. As with any medical treatment, it is critical that individuals with eating disorders consult with health care professionals and not pursue it on their own.
