According to the UNODC report, the highest prevalence of opioid use disorders in India is observed in the eastern parts of the country. Here are some key points regarding the findings:

• Eastern India has been identified as the region with the highest rates of opioid use disorders in the country.
• The states of Bihar, West Bengal, and Jharkhand in particular have reported the highest prevalence of opioid use disorders.
• These states are known for their proximity to the 'Golden Crescent' region, which is a major opium-producing area in neighboring countries.
• The easy availability and relatively lower cost of opioids in these areas may contribute to the higher prevalence of opioid use disorders.
• This prevalence study by the UNODC highlights the need for targeted interventions and strategies to address the opioid epidemic in eastern India.

It is important for local authorities, healthcare professionals, and communities to work together to develop comprehensive prevention, treatment, and harm reduction programs to combat this issue effectively.
