CBD Side Effects — what you should know
CBD is generally well tolerated. Still, there are side effects and interactions you should know before regular use — especially if you take medication.
The WHO considers CBD safe and non-addictive. Common, usually mild side effects: tiredness, dry mouth, appetite changes, mild blood pressure drop, occasional diarrhoea. Important: CBD inhibits liver enzymes (CYP3A4/CYP2C19) — it can affect how drugs are broken down. On prescription medication: talk to your doctor.
Common, mild side effects
Tiredness or drowsiness — especially at higher daytime doses.
Dry mouth — cannabinoids affect saliva production.
Drug interactions
CBD inhibits cytochrome P450 enzymes (CYP3A4 and CYP2C19), which metabolise many drugs. Drug effects can be amplified — comparable to the grapefruit effect.
Caution especially with: blood thinners (e.g. warfarin), antiepileptics, some antidepressants, benzodiazepines, immunosuppressants, some statins and PPIs.
When CBD is not appropriate
Pregnancy and breastfeeding: safety data insufficient — not recommended.
Under 18: no use without medical indication.
Quality cuts risk
Many «side effects» of cheap online CBD are actually contaminants: pesticides, heavy metals, synthetic cannabinoids. Clean, lab-tested Swiss CBD drastically reduces this risk.
Every batch on CannabisClub.ch has a viewable lab certificate.
