Patient Questions

Possible side effects of THC include:

Psychomotor and cognitive effects
• Impairment of short‑term memory
• Reduced attention, reaction time and coordination

Physical effects
• Increased heart rate, drop in blood pressure
• Fatigue
• Dizziness, dry mouth, red eyes

Psychological effects
• Strong restlessness
• Panic attacks
• Altered state of consciousness
• Psychotic symptoms

Interactions may occur with the following substances:

  • Medications metabolized via the cytochrome P450 enzyme system
  • Sedative or muscle‑relaxing medications
  • Alcohol
  • Herbal medicines

How quickly the medication takes effect depends strongly on the product itself and on the individual patient. With inhalation (e.g., cannabis flowers), the onset of action is approximately 5 minutes. With oral intake (e.g., extracts or dronabinol drops), onset typically occurs after about 30 to 90 minutes.

The effects of the medication are individual and must be discussed with a physician.

Terpenes are aromatic compounds found in the cannabis plant that determine its scent and aroma and may also positively influence the effects through the “entourage effect.” Different terpenes such as myrcene, limonene and pinene can have relaxing, mood‑enhancing, or anti‑inflammatory properties, which may complement the therapeutic effects of cannabis.

Cannabis products should not be taken in the following cases:

  • Pregnancy and breastfeeding
  • Schizophrenia or psychotic disorders
  • Hypersensitivity to cannabis
  • Children and adolescents
  • Risk of addiction or existing substance use disorders
  • Severe cardiovascular diseases

In Germany, the maximum legal limit for THC (tetrahydrocannabinol) in the blood when driving is 3.5 nanograms per millilitre of blood serum, provided there is no noticeable impairment in driving behaviour. This threshold is often used as a reference value to determine whether a person is considered to be under the influence of cannabis.

There is no specifically defined, legally binding limit for THC in urine, as the concentration of THC in urine does not directly correlate with impairment at the time of driving. Instead, THC levels in the blood are generally used to assess driving fitness.

The dosage of the medication is individual and must be discussed with a physician.

Cannabis products can be administered in the following forms:

  • As dried flower
  • As tea
  • As an extract in an oil‑ or alcohol‑based solution
  • As finished medicinal products, e.g., suppositories or ointments

The intake of the medication is individual and must be discussed with a physician.

Cannabis products should not be taken during this time.

It is recommended that medical cannabis be vaporized and inhaled rather than smoked. Smoking can produce harmful combustion by-products that may affect treatment. Other forms of administration (typically oral) should be discussed with a physician.

Medical cannabis is only covered by health insurance after a formal application has been submitted and approval is granted on a case‑by‑case basis (also referred to as a “prior authorization requirement”). Both private and statutory health insurers generally provide an application form that must be completed by the treating physician.

Adults are permitted to possess up to 25 grams per day and no more than 50 grams per month, while individuals aged 18 to 21 may possess no more than 30 grams per month, subject to a restricted THC content.

Physician Questions

Possible side effects of THC include:

Psychomotor and cognitive effects

  • Impairment of short‑term memory
  • Disturbance of attention, reaction time and coordination

In general, the use of cannabis does not necessarily lead to dependence. The addictive potential of cannabis tends to be lower compared to other intoxicating substances. Nevertheless, there is a possibility that patients may develop dependence — including on prescribed medical cannabis. Both the patient and the physician should be aware of this risk. Ultimately, it must always be evaluated on a case‑by‑case basis whether continued cannabis treatment is appropriate if dependence exists or appears to be developing.
The decision to initiate therapy with medical cannabis lies solely with the physician. Cannabinoid‑based medications can be prescribed using:
  • a statutory health insurance prescription
  • a private prescription
For health insurance coverage, a special application must be submitted. The treating physician must complete a form known as the “physician questionnaire.”
The primary applications include the treatment of chronic pain, particularly in conditions such as neuropathy or cancer. They are also used to alleviate nausea and vomiting in chemotherapy patients and to stimulate appetite in individuals with HIV/AIDS. In addition, there is evidence supporting their use in certain forms of epilepsy and in the treatment of spasticity associated with multiple sclerosis.
It is important that the use of cannabis products is carried out under medical supervision to maximize effectiveness and minimize potential risks.

Since April 1, 2024, cannabis products (flowers and extracts) no longer fall under the German Narcotics Act (BtMG). However, a prescription is still required to obtain cannabis.
Possible contraindications include:
  • Pregnancy and breastfeeding
  • Schizophrenia and psychotic disorders
  • Hypersensitivity to cannabis
  • Children and adolescents
  • Risk of addiction or existing substance use disorders
  • Severe cardiovascular diseases
The dosage of the medication must be individually adjusted to the patient.
The intake of the medication is individual and must be discussed with a physician.

A distinction is primarily made between flowers and extracts. Flowers can be smoked, vaporized and inhaled, or consumed as tea. Extracts are taken as oil‑based or alcohol‑based solutions. The specific method of administration, dosage and product must always be agreed upon between the patient and the physician.

This depends on the individual needs of the patient.

Characteristics of flowers (cannabis flos):

  • Strong but rather short‑lasting effects
  • Suitable for acute pain or sudden symptom flare‑ups
  • e.g., migraines
  • e.g., pain peaks
  • Versatile applications
  • Wide variety of strains (genetics, terpene profiles)
  • Different / high concentrations of active ingredients
  • Various combinations of active substances

Characteristics of extracts:

  • Slow but long‑lasting effects
  • Suitable for persistent or chronic symptoms
  • Sleep disturbances due to nighttime discomfort
  • Suitable for specific patient groups:
    • Geriatric patients
    • Palliative care patients
    • Patients with motor impairments
    • Working patients
  • (discreet intake / long‑lasting and steady effects)

Cannabis products should not be taken during this time.

Medical cannabis may be particularly helpful for patients with the following conditions:
  • Chronic and neuropathic pain (e.g., fibromyalgia)
  • Spasticity in multiple sclerosis
  • Nausea and vomiting associated with chemotherapy
  • Loss of appetite and cachexia in cancer or HIV/AIDS patients

Shelf life and storage conditions vary depending on the product, extract, flower and batch and are indicated on the respective packaging. In general, products should be stored in a dry, dark place at room temperature.

The patient must present a prescription in printed or digital form (e‑prescription) in order to receive medical cannabis.

For medical cannabis prescribed on a prescription, the quantity dispensed must correspond to the amount specified by the physician; the maximum prescribing limit is 100 g per month. In justified exceptional cases, the prescription must be marked with an “A” by the physician.

Cannabis plants can be genetically classified into three main categories:

  • Indica
  • Sativa
  • Hybrid

Indica varieties often have a more relaxing, calming effect, which makes them popular for evening use.

Sativa varieties tend to have more uplifting, energizing effects and may promote creativity, which is why they are often used during the day.

Hybrids are crossbreeds of Indica and Sativa strains and can exhibit characteristics of both, often resulting in a more balanced effect. Because of this, hybrids may be suitable for both daytime and evening use.

This classification helps consumers better understand the expected effects of a particular strain.

Terpenes are aromatic compounds found in the cannabis plant that determine its scent and aroma and may also positively influence the effects through the “entourage effect.” Different terpenes such as myrcene, limonene and pinene may have relaxing, mood‑enhancing, or anti‑inflammatory properties, thereby complementing the therapeutic effects of cannabis.
