Although physical health is not directly affected by a child's mental state, children with mental health problems are more prone to having a chronic health condition, which will follow them until adulthood. Of all children with a mental illness, forty percent have two or more mental illnesses. A child with a mental illness is more likely to develop even more mental illnesses as an adult. An adult with one or more mental disorders is less likely to work or participate in the community in a positive light (cdc.gov). The large number of children who have had problems in school, who get along well with their peers, and who become estranged from their families due to mental illness are unlikely to attend school or work in adulthood. Because these adults do so little, they are more likely to turn to substance abuse (NHPF.ORG). According to the National Bureau of Economic Research, the population of people with mental illness consumes 38% of alcohol and 44% of cocaine (dual diagnosis). ADD END
