A new study has warned that petrol-sniffing may reduce the growth of children permanently and there is no way to catch up even after they stop sniffing. A team of researchers, including those from Florey Institute of Neuroscience and Mental Health, looked at data collected from 118 males in two indigenous communities in Northern Territory in Australia.After two years, the males were found to be an average six centimetres shorter than their non-sniffing peers in the same community. The study showed that normal weight gain was also affected in the study participants. Researchers said, petrol- or solvent-sniffing addiction is a serious and widespread phenomenon amongst adolescent population. These substances are relatively easy to obtain, both over the counter and illegally. In the study, adolescents were sniffing around 250 millilitres (mL), a standard cup, of petrol every night. The worst-case consequence from inhaling is sudden death from a lack of oxygen. Beyond that, inhalants have been classed as more physically harmful than psychoactive drugs like GHB, ecstasy, cannabis and LSD. Rose Crossin, one of the lead researchers from the Florey Institute of Neuroscience and Mental Health in Australia said,”This is the first time that growth impacts have been measured and observed into abstinence.” She hopes the findings can be used to help health practitioners and families detect if children are sniffing petrol.
