Three Westport people have been charged with selling legal highs without a licence.
Police executed two search warrants at Westport addresses in relation to the illegal sale of psychoactive substances, commonly know as legal highs, on February 25, said police communications manager Barbara Dunn.
Senior Constable Paul Sampson had been dealing with public concerns regarding the use and supply of legal highs in the Westport community, she said.
Public concern at the effects the substances were having on the community had been raised through various sources, including social media and public meetings.
West Coast area commander Inspector John Canning made it a priority to investigate and take the appropriate action if offending was identified, Ms Dunn said.
