CBD and occasional anxiety: what the science says

The framework is set by MILDECA and by European regulation 1924/2006 on health claims: no therapeutic claim is entered in the European register for cannabidiol. Asserting that "CBD relieves anxiety" opens the door to reclassification as a medicine by presentation, within the meaning of article L.5111-1 of the Public Health Code. French brands therefore restrict themselves to non-therapeutic wellness vocabulary: "soothing ritual", "wellness approach".

The most frequently cited study remains that of Bergamaschi and colleagues (2011): 24 patients with social anxiety received 600 mg of CBD or a placebo before a simulated public-speaking exercise. The CBD group showed a reduction in the anxiety experienced and in heart rate. The sample was nonetheless small and the dose far higher than the amounts typically sold in shops. A later study by Linares (2019), at 300 mg, suggested a bell-shaped effect: neither a lower nor a higher dose was more effective in that protocol. On generalised anxiety or panic disorder, there is to date no large-scale clinical trial sufficient to ground a medical recommendation. The HAS maintains cognitive behavioural therapies as the reference treatment.

The endocannabinoid system partly regulates the stress response via the CB1 and CB2 receptors. Anandamide, produced naturally by the body, is thought to act as an emotional shock absorber; CBD partially inhibits the enzyme that breaks it down, FAAH, which could explain an acute anxiolytic signal. This mechanism nonetheless remains documented mainly in animals; its clinical translation in humans remains partial.

CBD has been legal in France since the decision of the Conseil d'État of 29 December 2022, provided the finished product contains at most 0.30 % THC. The synthetic cannabinoids HHC, H4CBD and THCP have been banned since 2024. For people who drive, a full-spectrum product can cause a saliva test for THC to come back positive: it is better to favour an isolate certified free of THC. CBD also inhibits the liver enzymes CYP3A4 and CYP2C19, which is reason enough to seek a pharmacist's advice in the case of long-term treatment.

Wellness CBD is not a suitable answer in cases of overwhelming anxiety lasting several months, recurrent panic attacks or marked social avoidance. In these situations, consult your GP or the "Mon soutien psy" scheme, which gives access to reimbursed sessions with a psychologist.

CBD is not a medicine. If anxiety persists or in the case of an anxiety disorder, consult a healthcare professional.

Does CBD really calm anxiety?

Legally, no authority permits that statement in France. Scientifically, a signal exists for acute anxiety at high doses, 300 to 600 mg, well above the amounts typically sold in shops.

What dose should be used?

There is no validated dose for anxiolytic use. Common practice is to start low, 5 to 10 mg sublingually, and to adjust gradually over several days.

Is CBD addictive?

The WHO judged in 2017 that pure CBD presents no potential for abuse or dependence. That does not remove the need for usage precautions, particularly if a treatment is under way.

Can CBD be combined with an antidepressant?

Not without medical advice. CBD inhibits certain liver enzymes that metabolise many psychotropic drugs, which can change their blood concentration.
