Which option best describes the health and societal impact of Class A drugs?

• A. Economic costs
• B. Addiction and dependence
• C. No impact
• D. Only physical harm

Answer: (B)

The health and societal impact of Class A drugs is best understood through addiction and dependence. When individuals become dependent, use tends to be chronic, elevating health risks such as overdose, cardiovascular and mental health problems, and infectious diseases if injecting. This dependence also drives wider social harms: crime to fund the habit, violence in drug markets, and pressure on emergency services, healthcare, housing, and employment. Because the question asks about both health and societal effects, focusing on addiction and dependence captures the ongoing health damage and the broader social consequences, making it the most comprehensive description. The other options only touch on parts of the impact: economic costs are important but don’t fully describe health and social harms; there is clearly an impact, and limiting to only physical harm misses the mental health and social consequences involved.
