According to The Conversation, a recent study analyzed national data on children and adolescents aged 6 to 19 in the United States. The results showed that children exposed to secondhand smoke had a blood lead concentration of 18% to 29% higher than those with less exposure. Millet is a neurotoxin that can damage the brain and reduce cognitive ability.
The effects of secondhand smoke are particularly serious in children aged 6 to 10, when the brain and nervous system are developing rapidly. Children from low-income households are also at higher risk, with lead levels in the blood 27% higher than children from well-off families. This shows that inequality in the living environment contributes to increasing the risk of mental Development2.
Toxins in cigarette smoke are not easily excreted from the body. They build up in bones and gradually absorb into the blood, causing irreversible nerve damage. Children with long-term exposure can have memory loss, loss of concentration, decreased IQ, and even increase the risk of neurological diseases such as Alzheimer's or mental disorders.
Passive cigarette smoke not only causes respiratory diseases but also silently destroys children's intellectual development. This is a strong warning that no level of contact is safe. Building a smoke-free living environment - from family to school - is an urgent step to protect future generations.
