Two men, aged 25 and 34, and a 24-year-old woman are due to appear at Falkirk Sheriff Court on Friday.
Detective inspector Norrie Petrie from Falkirk CID said: “Operations such as this disrupt criminal activity as well as addressing the concerns raised by local people.
“Crime has a detrimental impact on local areas and I would like to reassure people that we will continue with these proactive operations, demonstrating our commitment to ridding communities of crime and its associated impact.”
