Most young people in Nigeria commonly abuse three major drugs - codeine, rohypnol and cannabis - says Dr Vincent Udenze, founder of Synapse Service, a centre for psychological medicine.
The conclusion came from treating young adults battling drug addiction over a long period of time.
Dr Udenze said unfortunately most young people abusing drugs are reluctant to admit to the dependence or abuse until confirmatory tests including quick urine tests are conducted.
Speaking to students at Baze University, Abuja at an interactive session on the recent World Mental Day, Udenze said young people commonly turned to drugs under the influence of peer pressure or when dealing with low self esteem.
When young people become dependent on drugs, he noted, their families were usually the last to know which, according to him, was quite unfortunate.
However, he observed, treatment should target entire family of the drug-dependent youth, not just the individual saying that was the best way to ensure that the treatment becomes effective.
"Parents are part of the treatment cycle, and have to be there," Dr Udenze said.
Udenze who is a psychiatric observed that Nigeria does not have number of psychiatrics needed to handle the huge number of persons suffering from mental health.
He also opined that over 30 per cent of the country's population suffer from mental health illness saying "unfortunately Nigeria has a huge shortfall of personnel when it comes to mental health, way below the required number in other developed countries."
