Medicine and risk at the same time.
Both are true.

Why this article is needed right now

Before we go into the biology, a picture has to land that many patients do not yet know in this form. Since 1 April 2024, cannabis has been removed from the German narcotics law and can be prescribed on a normal eRecipe. That was regulatory progress. What has come of it in practice needs explaining.

A large share of this boom runs through telemedicine platforms that issue cannabis prescriptions after an online questionnaire, often without a personal consultation, without a physical examination, without long-term follow-up. The German Federal Ministry of Health has reacted and plans to require at least one in-person initial contact before any cannabis prescription, plus a ban on mail-order sales of cannabis flower.

Why does this matter for you? Because a prescription alone is not therapy. A prescription without a doctor-patient relationship, without a diagnosis, without follow-up may do exactly what cannabis most often does: dampen a symptom while the cause keeps growing. The fact that it is fast and easy today to obtain a cannabis prescription does not mean it is the right therapy for you. It only means that the market has a very low entry barrier.

What cannabis really does in your body

Before we talk about benefit and risk, let us briefly look at the biology. Your body has its own cannabis system. It is called the endocannabinoid system, ECS for short. It regulates mood, pain, appetite, sleep, immune function and stress response. You have it long before you have ever thought about cannabis.

Two receptor families carry the system. CB1 sits mainly in the brain and nervous system. CB2 sits mainly on immune cells. Your body produces its own cannabinoids, especially anandamide, often called the "bliss molecule" because its name comes from the Sanskrit word for bliss.

Cannabis brings two main molecules into play. THC binds strongly to CB1, is psychoactive, has analgesic and appetite-stimulating effects. CBD acts indirectly on the ECS, dampens THC's effect, is not psychoactive, and has anxiolytic, anti-inflammatory and anticonvulsant effects of its own.

The mitochondria story: why fatigue comes from your cells, not from your head

Here comes the point that most patients hear for the first time. It is neurobiologically decisive.

For a long time, science assumed CB1 receptors sit only on the cell membrane of nerve cells. In 2012, Bénard's team found something else. CB1 receptors also sit directly on the mitochondria, the power plants of your cells. They are called mtCB1.

What does that mean in practice? The well-known cannabis aftermath of heaviness, sluggishness, low drive the next day is not psychological. It is not "I have just become lazier". It is less ATP in your brain cells. Your cells literally have less power. Consciousness slows down because the machinery that carries it has less energy.

On top of that comes a second layer. In chronic users, striatal dopamine synthesis is reduced, and that finding correlates directly with apathy scores. You are not losing drive because you are weak. You are losing it because your reward system is producing objectively less dopamine.

What cannabis as medicine can credibly do

Cannabis has clean medical indications. I prescribe it. The important caveat: not for everything, not in every form, not for every person.

Beyond that, there are smaller positive signals for CBD in social phobia (Bergamaschi 2011, Crippa 2011) and for cannabinoids in chemotherapy-induced nausea as a reserve option, when modern antiemetics fail. The evidence for sleep disorders and general anxiety is much thinner than marketing often suggests.

Where the evidence has gaps you should know about

Cannabis is often presented as a universal solution. For sleep, for stress, for anxiety, for "inner restlessness". Honestly, this is a marketing phenomenon, not a research finding.

For sleep disorders, cannabis has acute sedative effects, but chronic users develop tolerance. On withdrawal, sleep often gets dramatically worse (withdrawal insomnia), which keeps the consumption going without the underlying cause being addressed. For anxiety, CBD acts anxiolytically in low doses, while THC often produces paradoxical anxiety, especially at higher doses or in predisposed individuals. For depression and PTSD, the evidence is mixed, with signals that chronic use may worsen outcomes.

Addiction risk is biology, not weakness

Here it gets uncomfortable. Cannabis has a clearly documented addictive potential. To deny that is to whitewash.

On top comes the Cannabis Withdrawal Syndrome, officially recognized in DSM-5. About 12 percent of frequent users experience irritability, anxiety, sleep disturbance, depressed mood, appetite loss, sometimes sweating and tremor on cessation. The classic "I can quit anytime" is often relativised within the first week of quitting. Anyone who has experienced it physically knows: this is not willpower, this is pharmacology.

Two thresholds you must know: adolescence and high potency

There are two constellations where the evidence is so clear that minimisation no longer holds.

The anthroposophic view: cannabis and the awake "I"

From the perspective of anthroposophic medicine, the human being is threefold. There is the nerve-sense system (consciousness, clarity, alertness, differentiation). There is the rhythmic system (breathing, heart, feeling, the centre). And there is the metabolic-limb system (will, digestion, warmth, movement). Health is balance between these three poles.

Cannabis shifts this balance characteristically. It dampens the awake nerve-sense system and amplifies the dreaming, dissolving pole. In Steiner's language: it pushes the human being towards the luciferic pole, away from sharp differentiation. That is exactly what makes the subjective appeal: the "becoming softer", the "letting go", the "sliding into images".

For controlled, occasional use, this shift is not a problem. With chronic use, something else happens. The awake "I", the middle force that balances between dream and hardening, becomes quieter. Differentiation gets harder. Decisions get softer. Perception becomes less precise. The clinical observation maps strikingly onto the mitochondrial finding above: less energy for consciousness means a quieter awake "I".

PNI and functional medicine: root work instead of symptom dampening

Clinical psychoneuroimmunology does not look at the symptom but at four lenses: nervous system, immune system, metabolism, hormones. Cannabis dampens symptoms across all four lenses, without addressing the root cause.

If someone uses cannabis because they cannot sleep, the real question is not "does cannabis work for sleep". The real question is: why is your system not sleeping? Disrupted cortisol rhythm, blue light late at night, magnesium deficiency, unresolved conflict, caffeine-driven day, no morning daylight, mitochondrial weakness, inflammation, late sugar? That is PNI work. Cannabis helps short term. The causes do not change.

If someone uses cannabis for chronic pain, the question is: which of the four PNI lenses drives this pain? Nervous system on permanent alarm? Silent inflammation? Tissue mitochondrial weakness? Hormonal shifts? Here too, cannabis dampens. Roots remain untouched.

From a functional medicine perspective: any symptom dampening that is not combined with root work costs more long term than it saves short term.

How I work with cannabis in my practice

I do prescribe cannabis. But rarely as a first lever. And never without a clear diagnosis, without a personal consultation, without longer-term follow-up. There are three patient constellations where I actively consider cannabis as a therapy tool.

What I have to say just as clearly: in the vast majority of cases where patients come to me asking for cannabis, the indication is not unambiguous. It is about sleep problems, stress, anxiety, diffuse pain, "I do not know how to come down anymore". For these themes, cannabis is in my view almost never the first choice. Not because it does nothing, but because other paths are demonstrably more sustainable and carry no addiction risk.

Other paths by indication

If you feel cannabis is the only thing that helps you, let us go through the evidence indication by indication. For the most common reasons people seek cannabis today, there are paths with better long-term evidence and no addiction risk.

Pain

Sleep

On top come the basics that many patients underestimate: dark, cool bedroom, no screens in the last hour before sleep, regular sleep times, magnesium in the evening (may support falling asleep), no caffeine after 2 pm, daylight in the first hour of the day for the cortisol axis. PNI-aligned additions: check the cortisol day profile, avoid evening blood sugar swings, surface unresolved themes instead of deckling them with a substance.

Stress and chronic overload

Stress is the most common self-justification that brings people to a joint in the evening. The evidence here is straightforward: there are three methods that, in direct comparison, work equally well, without addiction risk, without mitochondrial dampening, without sleep deterioration over time.

On top come the slower, deeper levers: anthroposophic compresses (lavender abdominal compress in the evening), warmth applications, contact with nature (a walk in the forest demonstrably reduces cortisol), relational clarity, honest communication. Whoever uses cannabis against stress dampens the symptom. Whoever works on these points relaxes the system.

Anxiety and inner restlessness

The most effective non-pharmacological levers: coherent breathing (four seconds in, six seconds out, five minutes daily) regulates the vagus nerve and measurably raises HRV. Mindfulness and MBSR reduce anxiety and pain with small to moderate effects across more than 30 RCTs. Exercise works as antidepressant and anxiolytic via endocannabinoids and BDNF. Targeted psychotherapy at the roots (trauma, conflicts, relationships) works more sustainably than any substance.

For generalised anxiety, the PNI lenses are worth checking: low magnesium may increase neuronal excitability, low vitamin D is associated with higher anxiety prevalence, thyroid and iron co-determine the tone. If one of these is off, even the most relaxing joint will not help sustainably.

Trauma and post-traumatic stress

This is where cannabis is particularly often used on personal initiative, with partly understandable subjective effects. The evidence shows a clear gap between subjective experience and durable healing.

What has real impact in trauma: EMDR (Eye Movement Desensitization and Reprocessing) with evidence from 24 RCTs, in several comparisons even faster than trauma-focused CBT. Trauma-focused CBT with prolonged exposure as first-line therapy. Somatic Experiencing as a body-oriented approach, especially for dissociative parts. EAET (Emotional Awareness and Expression Therapy) for somatised trauma sequelae with chronic pain. These methods work with the trauma. Cannabis works around it.

If you are young and use cannabis against life-feel themes

A particular constellation, because it is especially common today. Younger adults between 18 and 28 who use cannabis against "inner emptiness", "meaninglessness", "lack of depth", "too much overstimulation". Three points are important here: first, the adolescent and early-adult brain is in a critical maturation phase until the mid 20s. Second, high-potency material is in this constellation the largest risk factor for a first psychotic episode. Third, what often feels like "inner emptiness" is very often an unanswered hunger for meaning plus a measurable biological depletion (sleep, micronutrients, lack of movement, screen time, missing relational depth).

The most honest therapeutic answer here is a mixture of relational therapy, PNI diagnostics (thyroid, cortisol profile, vitamin D, iron, microbiome), physical activity, meaning work, and where appropriate anthroposophic support. Cannabis can soften this experiential gap acutely. It does not fill it.

If you want to come off cannabis: what really helps

Anyone who uses regularly and wants to stop knows the pattern: a few days go well, then come sleep problems, irritability, vivid dreams, restlessness, the gnawing craving. Most self-quit attempts last less than a week. That is not weakness. That is withdrawal. It usually fades within two to four weeks, but the first ten days are hard.

You do not have to fight against the substance. You have to give the system what it expected from cannabis: calm, sleep, reward, meaning. By another route.

Three honest levers for your self-check

First lever. Ask yourself the honest question: if I stop today, would I feel free energy, or a loss? If the answer is "loss", that is not proof that cannabis benefits you. It is proof that your system has adapted to the substance. That is exactly the definition of dependence.

Second lever. Breathe coherently for five minutes a day (four seconds in, six seconds out). This single exercise measurably raises your HRV in studies and lifts your endogenous endocannabinoid tone. You build up internally what you would otherwise take from outside.

Third lever. If you use cannabis, do it consciously, not reflexively. Never daily. Never as a permanent sleep aid. Never against stress that actually needs processing. Never in adolescence, never with a family history of psychosis, never daily and high-potency. If those lines are held, cannabis remains an occasional tool. If they blur, it becomes a load that your system measurably pays for.
