The child has been put up for adoption after a judge heard the family home was engulfed in a 'visible cloud of smoke.'
Health visitor Julie Allen, who visited the property, said she had never seen such a smoky house in the whole course of her career.
The boy, who cannot be named, already has to use an inhaler to cope with breathing problems, something no doubt exacerbated by the smoky atmosphere.
The judge said: 'On entering the living room Ms Allen described being able to see a visible cloud of smoke. [The boy] was asleep on the sofa and had been unwell for some time. Ms Allen described the room as "so smoke entrenched I had difficulty breathing."'
It was also reported that the general condition of the house was poor, that it was dirty and unhygienic.
Drug paraphernalia was also found on the premises and the father tested positive for cocaine.
