Eight men were facing jail last night after a trial which followed two police raids on a North-East house.
Five of those arrested were Jamaican nationals who travelled from London claiming they were visiting girls or in the area to buy cheap cars.
Police found crack cocaine when they raided the house, in Walpole Street, Middlesbrough, after filming visitors.
In two nights, they logged more than 100 people going to the house. Only three people seen on the street were not on their way there, said Graham Reeds, prosecuting at Teesside Crown Court.
In the two raids, officers arrested the owner, Silmouth Brown, 56, his son, Dean Nixon, 22, and five men from London, said Mr Reeds.
Brown and Joseph Flemings, 19, of Craven Park, London, admitted conspiracy to supply crack cocaine between March 13 and April 30 last year. They were remanded in custody for sentence later.
Nixon, 22, of Laycock Street, Middlesbrough, Michael Ridguard, 61, also of Walpole Street, Middlesbrough, Kirk Wilson, 26, and Julian Ford, 24, both of New Cross, London, and Paul Barrett, 24, and Herbert Thompson, 31, both of Margrove, London, were all found guilty of conspiracy to supply.
They were remanded in custody for reports.
