A mum and dad dealing amphetamine from their Bristol home contaminated their own children with the drug.
Police who raided the Knowle property found drugs stashed in the bathroom and kitchen.
Some drugs were even being stored in sweet tubs, Bristol Crown Court heard.
When several youngsters under 13 had samples of their hair analysed, they tested positive for exposure to amphetamine.
Bristol Live is not naming the parents to protect the identities of the children.
The mum, aged 38, and the dad, aged 37, both pleaded guilty to possession with intent to supply Class B drugs amphetamine and cannabis on the day of a planned trial.
Four charges of child cruelty concerning the youngsters, who are now all in local authority care, were left to lie on file.
