Depression: Causes, symptoms, experiences & medical cannabis

Depression is one of the most common mental illnesses worldwide. According to the AOK, almost 9.5 million people in Germany are affected. The symptoms range from persistent depression to sleep disorders and listlessness. Techniker Krankenkasse points out that early treatment is important in order to avoid long-term consequences. In addition to traditional therapies such as psychotherapy or antidepressants, medical cannabis with THC is increasingly being discussed as a supplementary option.

How depression develops and which symptoms are typical

Depression is not a “bad mood”, but the result of complex interactions between genetic factors, stress, hormonal changes and environmental influences. An imbalance of important neurotransmitters such as serotonin, dopamine and noradrenaline is often at the heart of the problem. Serotonin in particular plays a key role in mood, motivation and sleep. If the level is permanently low, this can trigger or intensify depressive symptoms.

• Persistent despondency and hopelessness
• Loss of interest in everyday activities
• Sleep disorders or excessive tiredness
• Loss of appetite or increased appetite
• Difficulty concentrating
• Physical complaints such as headaches or stomach problems

How THC works in the brain and why it can help

THC interacts with the endocannabinoid system, which regulates mood, sleep and appetite. It binds to CB1 receptors in the central nervous system and can modulate the release of dopamine and serotonin. Functional MRI studies show that THC affects emotional networks in the brain, particularly the amygdala and the prefrontal cortex(Bossong et al. 2013). These changes can lead to relaxation, mood-enhancing effects and better sleep in the short term.

• Can influence serotonin and dopamine levels
• Can have a relaxing and mood-enhancing effect
• Can help with sleep problems

What studies on THC and depression show

Research on cannabis and depression differentiates between short-term mood enhancement and long-term effects. Low doses of THC can temporarily alleviate depressive symptoms, while high doses increase the risk of anxiety or moodiness. An experimental study showed that low doses of THC significantly improved mood, while higher doses had the opposite effect(Dahlgren et al. 2017). A systematic review came to the conclusion that cannabinoids can play a role as an add-on, especially for treatment-resistant symptoms(Strohbeck-Kuehner et al. 2021).

In addition, observational studies indicate an improvement in sleep quality and stress levels under controlled medical cannabis use(Cuttler et al. 2020). However, cannabinoids do not replace guideline-based therapy, but can be used as a supportive measure.

• Can improve mood and sleep in the short term
• Can reduce anxiety (at low doses)
• High doses can have the opposite effect

Experiences: How THC can help in everyday life

Many people with depression report positive experiences with THC, particularly in terms of drive, sleep quality and emotional stability. These subjective experiences are partly consistent with results from clinical studies, which show an improvement in mood and stress management.

Lisa B. from Dessau, 32:

“I’ve been struggling with depression for years. Medication didn’t really work for me. After my doctor prescribed me medicinal cannabis, I feel more balanced and can sleep better again.”

“I had a lot of trouble getting out of bed in the morning. THC helps me to start the day better without feeling woozy.”
