People who take CBD supplements often report feeling relaxed or calm, and although these products shouldn’t contain THC that’s linked to feeling “high,” strong doses of CBD may make you feel lightheaded, or “blissful,” while the chemical enters your bloodstream. Side effects of CBD may include:
Nausea.
Fatigue.
Irritability.
Dizziness.
Dry mouth.
Diarrhea.
Changes in appetite.
