The bar name says it all really like any big town in thailand.But a tourist town like pattaya the police know when to check and what to look for.I heard stories about bars in bkk a disco and everyone is checked if anyone is peeing purple then u are going nowhere.Farangs are checked but mostly thais are checked.My friend got checked in cnx don,t know where, she had to do a test once a week to the police untill clear.No charges really just a gov record of rehab,I think it was about 1 mth of checks
