When the Craven Country Jamboree winds down a Regina clinic of Planned Parenthood expects to gear up.

Christine Smith, director of Planned Parenthood Regina, says the clinic has seen an influx of patients every year following the country music show, west of the city.

According to Smith, many people are seeking advice on sexually transmitted infections, or STIs.

"After the event is complete, we usually see an increase in people coming to the sexual health clinic for STI testing and pregnancy testing," Smith told CBC News.

The agency also provides information to people on the festival site, and includes pamphlets and condoms.

"It's a big event," Smith said. "You know you can't control people, so you really just have to make things available."

Smith says the number of patients the clinic sees usually goes up about 20 per cent after the festival.

Smith said there can be a lot of unprotected sex at the jamboree, where people let their guard down because of the party atmosphere.

While people attend the festival to have fun, Smith said things can turn serious.

She says festival-goers should bring condoms and be cautious, and watch their drinks closely as drugs can easily be slipped into opened beverages.

Around 23,500 country music fans are expected at the Craven-area show which runs three days.
