A prison is electronically scanning all incoming mail to combat attempts to smuggle drugs in on cards, photographs and bogus legal letters.
The screening arrangements were introduced to cut off the flow of illegal substances via "impregnated" correspondence into HMP Ranby in Nottinghamshire.
New psychoactive substances - synthetic drugs previously known as "legal highs" - were the "clear drugs of choice", HM Inspectorate of Prisons found.
The report said: "The primary route into the prison of NPS and other substances was through impregnated letters (including false legal correspondence), cards and photographs.
"All incoming mail was electronically scanned for drugs and we were satisfied that the robust restrictions that applied when a test was positive were proportionate."
The report on HMP Ranby said that, while the screening of all mail was "proportionate", it often delayed delivery by up to 48 hours. Drug finds and positive tests at the prison had decreased over the previous year, and longer-term analysis showed a reduction since it was last inspected in 2015.
"Despite this, incidents involving NPS were common and we saw prisoners under the influence of NPS throughout the inspection," the inspectorate said.
Overall, the assessment concluded there had been a clear improvement at the category C facility, which holds about 1,000 men.
