Dr Singh says healthcare workers should start identifying mental health symptoms early, as untreated anxiety, depression and stress can lead people towards substance abuse.
She says mental health and medical conditions such as diabetes and hypertension are closely linked, as people struggling mentally are less likely to follow treatment plans, maintain healthy lifestyles or attend clinics regularly.
Dr Singh says doctors and healthcare workers should include simple mental health screening questions when checking patients for illnesses, such as diabetes and hypertension.
She is also encouraging medical professionals to approach people battling addiction with empathy rather than criticism.
She says many drug users avoid seeking help because of stigma and fear of being judged.
The psychiatrist also calls for stronger rehabilitation support within communities and health facilities, saying rehabilitation is not only about buildings, but also about listening, counselling and family support.
Dr Singh says hospitals alone cannot fight the growing drug problem and all health professionals and communities need to work together.
