Gardai made 40 minor drug seizures in Ballyshannon over the weekend during the Rory Gallagher Festival.
The detections related to simple drugs possessions during the four day music festival which attracted approximately 12,000 fans.
The 40 seizures are reported to be down on previous years and were all for small amounts. There were 27 arrests for simple cannabis possession, compared with 57 arrested last year.
There was nobody arrested or detected with drugs for sale.
Although the drug seizures were down, public order offences were up to 15 compared with 10 last year. All those arrested have been released and will be dealt with by way of summons.
The festival, which pays tribute to the legendary guitarist, attracted fans from as far away at Switzerland and Scandinavia.
The headline act was former Rolling Stone Mick Taylor, as well as Dr Feelgood and Horslips - over 30 acts played the four day festival.

Gallagher recorded solo albums throughout the 1970s and 1980s. Known for his charismatic performances, Gallagher’s albums have sold in excess of 30 million copies worldwide.
