Two brothers have each been sentenced to 11 months in prison after £130,000 worth of drugs were found in their Berkshire home.
Kamil Kalwajtys, 27, and Lukasz Kalwajtys, 24, of Furzen Close, Slough, pleaded guilty to possession of amphetamines with intent to supply.
The brothers were arrested at Bullingdon prison, Oxfordshire, in March when they visited an inmate.
They were sentenced earlier at Oxford Crown Court.
Lukasz Kalwajtys was also sentenced to a month in prison for possession of a class B drug, cannabis, and a month for possession of a class C drug, both to be served concurrently.
Thames Valley Police said after the arrests that when officers searched the brothers' home they found a rucksack containing 1.6kg (3.5lb) of amphetamines, 24.9g (9oz) of herbal cannabis, drug paraphernalia and mobile phones.
