Greg began selling the product 12 months ago and had been busy with it since, he said.

A Tease Adult Shop's Vanessa Gibson said business was booming with new faces in addition to her regulars and she supported new regulation.

Both stores were busy with countless purchases of synthetic cannabis yesterday.
Alvan Pearson, who received the Western Bay's only licence for wholesale, said he chose to apply because he wanted his business in the "smoking range" to continue. he buys synthetic cannabis in bulk and sells it on.
He was happy regulations mean it was not being sold in dairies, despite labelling the product as safe and "low impact".
The owner of Bamboo Barn declined to comment.
Puff n' Stuff in Cameron Rd was one of the applicants "under consideration".
Owner Mike Lawrence removed its bread and milk and said the wait for a licence was over clarification about a coffee machine in the store.
Another retailer said she applied only because her supplier paid the bill.
Each retailer said they were aware of dairies and other outlets continuing to sell the product despite the new law.
Inspector Karl Wright St-Clair said Western Bay of Plenty police were working with the Ministry of Health and Bay of Plenty District Health Board to monitor and investigate any information alleged breaches.
Anyone concerned at retailers selling the product without a licence can contact police on 07 577 4300 or 0800 Crime Stoppers.
