Needle bins are being put in new public toilets in Carmarthenshire to tackle the problem of discarded syringes.
The needle bins have been placed at nine locations
There had been concerns members of the public and council staff were at risk of pricking themselves on dumped needles left by drug users.
The council said the move would also benefit people such as diabetics who have to administer their own insulin.
They have been placed at nine locations in the county where the council has refurbished its public toilets.
The authority's principal engineer, Roger Morris, said: "We have provided nine 'superloos' within the county as part of the update programme for public conveniences.
"They offer a very high standard of facility and there is a chute for the disposal of syringes in each cubicle.
"This chute feeds into a needle stick box located in the service area which the public do not have access to.
"The syringes are then disposed of as clinical waste.
"We deem this service to be preferable to such items being deposited on public floors where they could pose a danger to staff and the public."
He said the bins were not just for illegal drug users.
"This is also an important service for people such as diabetic sufferers who administer their own insulin and it allows them a disposal route that is both safe and convenient," he added.
The move has been supported by Dyfed-Powys Police.
