Police seized a huge machete, a meat cleaver and bags of pills during multiple raids across flats in Govanhill.
Glasgow police descended on the tenements on Boyd Street armed with search warrants yesterday morning.
The move followed tip-offs from the public about possible drug dealing in the south side of the city.
Officers broke in and found two people in the flat, which had a wooden implement behind it to stop people getting in.
A large machete was in the hall and a meat cleaver was found elsewhere.
Following an hour-long search, two large bags of tablets were found, these will be sent to police labs for testing.
A woman was arrested in connection with an outstanding warrant relating to another matter. She was taken into custody.
In the last property, someone inside surrendered a machete and a meat cleaver but no drugs were found.
Inspector Cennydd Smith said: "Tuesday's action was a culmination of community engagement over a period of time that has allowed us to execute three drugs' warrants.

"As a result of these warrants we have taken four potentially lethal weapons of the streets and will carry out tests to establish the nature of the tablets recovered.
"Hopefully this provides the local community with the reassurance that we act on their concerns and those involved in the supply of controlled drugs will not be tolerated.
"If anyone has any concerns about drug dealing in their area then they can contact Police Scotland on 101 or Crimestoppers can be contacted anonymously on 0800 555 111."
