How we use sources
Sources are used to support clinical and safety statements, but pages are written in original plain language rather than reproducing guidance. Additional peer-reviewed evidence will be added as topic pages become more detailed.
This page provides general educational information and does not replace assessment or advice from a healthcare professional. If you are worried about severe withdrawal, overdose, immediate danger or a mental health emergency, use our urgent help guidance.
