Sefton Central Labour MP Bill Esterson said he was shocked to discover the remnants of a cannabis farm dumped on a country road in Thornton.
Bill made the discovery while making a site visit to look into reports of illegal flytipping off Holgate in Thornton and Back Lane in Lunt.
The MP said he was shocked at what he found.
Bill said: "I was contacted by residents who had concerns about illegally dumped rubbish in the country roads between Thornton and Lunt.
"When I visited the scene, I discovered what appears to be discarded drug farm paraphernalia. The spot had already been visited by Sefton Council's cleansing team who had left behind a notice to say they had taken away evidence for the investigation into flytipping.
"I have contacted the police to let them know that some of the remnants could be from a drug farm.
"The police may be able to get evidence from it themselves."
Bill has also been working with Manor Ward Labour Councillor Steve McGinnity who has raised the issue with Sefton Council.
Cllr McGinnity said: "I have noticed a sharp increase in incidents of flytipping throughout Sefton in recent months.
"It isn't uncommon to see asbestos tiles dumped, or old tyres. But this is the first time I have heard of the remnants of a drug farm. That's just a whole new concern altogether.
"Bill has already raised this with the police and I will be checking with them to see if they have managed to trace the former owners who may well have a cottage industry on the go here in Sefton in producing drugs."
