"They should not have allowed sales of these drugs," she told anyone who cared to listen.
She later told Hamilton News she was all too familiar with the results of the use of so-called legal highs and knew of their effects on children.
Only last week a police sting operation saw the prosecution of a city business for breaching new legislation regulating synthetic cannabinoids.
Police visited six shops and one business sold a volunteer a synthetic cannabinoid product, as well as a soft drink, which is in breach of the Psychoactive Substances Act.
City councillor Angela O'Leary said she has asked council to fast track a policy to ban the sale of synthetic cannabis in the city 'before a proliferation of these "puff" stores become our community drug dealers'.
"Unfortunately new government law only goes half way. They have not made it easy on councils to mitigate the effects of legal highs and I get inundated with calls witnessing the anti-social behaviour that comes with it," she says.
"What's more baffling is the interim approval given by the Ministry of Health on the brands at the commencement of the new Act.
"It's like asking an alcoholic to complain about their own drinking." She says the National Poisons Centre has found an ingredient in at least five of those approved which causes hallucinations and psychosis. It's madness."
Waikato Regional Councillor Lois Livingston, who helped promote the protest, said the whole idea was to show the city council and the Ministry of Health, that 'we don't want these types of shops in our suburban villages'.
Livingston said the shop receives more than 200 customers per day who cause a lot of disturbance within the community.
She said high school kids waiting for their buses don't wait in the bus stops because they don't feel safe with these sorts of people hanging around.
"They are fighting in the streets and just causing trouble." she said.
Livingston wants the council to allocate a zoned area for the sales of the products.
Michelle Cuttance, owner of the Grey Street Kitchen, a cafe three doors down from the shop, said she wants it gone.
"Nobody wants it, full stop. But if it has to be here then take it somewhere else away from the public."
Michelles's co-worker Jane Johnston said the shop attracts 'undesirables'. "They are hassling our customers for money. And we're getting complaints from customers who don't enjoy having those sort of people around.
"It's no good," Cuttance said. "Nobody wants it here."
