Her comments follow the burglary of the shop early yesterday.
Senior Sergeant Bruce Ross, of Dunedin, said four youths aged 15 to 17 ''smashed'' into the Prince Albert Rd store at 3.30am.
A police dog and handler followed a track to a Young St house, where the four were arrested.
They were charged with burglary, he saidMs McKenzie said there had been a spate of antisocial behaviour in the area since the shop opened in August.
On September 16, two men wearing balaclavas and wielding baseball bats smashed the front window of the Supporting Families in Mental Illness office, two doors down from the shop.
She believed the senseless vandalism was retaliation for her being ''vocal'' about wanting the council to create exclusion zones for synthetic cannabis shops, so they could not sell around schools and mental health organisations.
''Whether it's illegal parking, kids on skateboards in the middle of the road, or people loitering, there has certainly been an increase'' in antisocial behaviour.''
