TWEED retailers have so far been found in full compliance with the ban on synthetic drugs introduced this week by the State Government.
NSW Fair Trading senior investigator Stuart Evans said inspections of local tobacconists, adults shops and other stores which began on Wednesday had so far detected no retailers still selling the substances.
The 90-day ban on synthetic drugs came into force on Monday after the death last week of Sydney boy Henry Kwan.
They had had a real spike in sales and requests for products since it became illegal in Queensland.
The 17-year-old jumped from his family's high-rise apartment after taking a substance that mimics the effects of LSD.
Mr Evans said it was mostly an information campaign at this stage to ensure stores were no longer selling or promoting the 19 banned products promoted as "legal highs" like Kronic, Skunk and Black Widow.
But he warned that there would likely be follow up inspections including covert operations with non-complying stores to face prosecution.
Mr Evans said retailers were "very apprehensive to say too much" but staff at two Tweed stores had advised they had done a brisk trade in the products to Queenslanders prior to the ban.
"They had had a real spike in sales and requests for the products since it became illegal in Queensland," Mr Evans said.
In late 2011, 19 new chemicals marketed as legal alternatives to cannabis were essentially banned in Queensland.
NSW Fair Trading minister Anthony Roberts has urged the federal government to help make the ban permanent and national.
