**Core Concept:** Criminal Justice Act 2006 is a UK law, and the 2009 amendment introduced changes to the existing legislation. Understanding the amendments helps medical students to appreciate the context and relevance of healthcare-related laws in the medical field.

**Why the Correct Answer is Right:** The 2009 amendment to the Criminal Justice Act 2006 introduced Section 135A to address healthcare-related issues. This section deals with the regulation of healthcare professionals, specifically doctors, dentists, and nurses, who are involved in the administration of controlled drugs to patients. Controlled drugs refer to substances that have strict regulations due to their potential for misuse or abuse.
