A pub is using airport-style security following reports of drinks being spiked in the area.
The dramatic new measures come as a spate of needle spikings sweeps the country.
The National Police Chiefs' Council (NPCC) said there have been 198 confirmed reports of drink spiking in September and October across various parts of England, Scotland, Wales, and Northern Ireland, plus 24 reports of some form of injection.
The worrying increase in reports of people being allegedly drugged has sparked a campaign group 'Girls Night In' to launch a boycott of venues across the UK throughout the week.
The Angel Inn, in Aberystwyth, started carrying out non-contact searching at the door on October 22, using handheld metal detectors to find needles as well as torches to look through bags and wallets as a response to the rising number of cases, WalesOnline reports.

Niamh Downes, 22, said recent reports of needle and drink spikings across the country were "terrifying" and the measures were implemented after a woman was reportedly spiked at the pub.
She added: "Everywhere at the moment has its issues, but because Aber is such a safe little town, it's particularly shocking up here.
"A couple of weeks ago, a girl was very unwell outside after leaving The Angel, and a member of our door staff drove her to A&E, where she was tested and it turned out she had been spiked with GHB.
"It takes 15 to 30 minutes for that drug to take effect, and she'd been in the pub for an hour and a half. We went through the CCTV and there was no obvious moment it happened.
"That was the main one that shocked all of us, where we sat down and thought, 'Okay, this is becoming really serious in Aber'."
Another member of staff at The Angel, who did not want to be named, said he was spiked while off-duty at the pub late on the evening of October 6.
"I don't leave drinks unattended, and I can't remember anything after my second pint," he said. "Once I went to bed, I slept 29 hours. I went to sleep on the Wednesday evening and woke up on Friday morning.
"People I was with said I hadn't been behaving in any way untoward or attracting attention or anything like that, but I have no memory at all. When I went to sleep I went time-travelling for 29 hours.
"I took normal precautions and it still happened to me."
Reports of people being spiked and rushed to hospital have come from Nottingham, Portsmouth, Cardiff and beyond.
One woman who alleges she was spiked claims the hospital told her she was not the first case that night.
Georgia Latham said she only had one drink in Cardiff's Pryzm nightclub on Friday night when she became ill, and claims she was told by medical staff she had likely been spiked with Rohypnol.
In a separate incident, Elizabeth Everett, from Warrington, claims her symptoms progressed to being "violently sick" before she eventually collapsed on a night out on October 16.
She feels the incident has had a lasting impact on her memory and is now wary about going out.
As the number of reports of spiking increases, many have claimed they were injected.
A young woman was rushed to hospital over the weekend in Portsmouth following reports she started feeling tenderness and numbness in her arm and noticed a pin prick injury.
The NPCC lead for drugs, Deputy Chief Constable Jason Harwin, said: "Clearly these reports are very concerning.
"We are working at pace with forces, law enforcement agencies such as the NCA and other partners including the Home Office and universities to understand the scale of offending, establish any links between the allegations and ultimately bring any identified offenders to justice."
