Queensland moves to seize assets of alleged Gold Coast King of Kronic's synthetic cannabis operation Matthew Wielenga in an image on his Facebook page. Matthew Wielenga leaves the watchhouse on bail after facing drug charges. A KIWI allegedly known as the ``King of Kronic" was behind the distribution of up to 6000 packets a day of synthetic cannabis from a Gold Coast base, according to documents filed in court. Matthew Wielenga's incredible operation is described in documents lodged by crime fighters seeking to seize his alleged proceeds of crime. Invoices totalling more than $500,000 were allegedly issued in less than a month in 2011 to retailers and individuals as Australia's demand for synthetic cannabis soared. His firm allegedly dispatched so much of the product that Australia Post staff became concerned at the flowery smell wafting from packages and called police. Company emails lodged as part of the court action also reveal turmoil within the firm as staff struggled to keep up with the volume of supplies. ``I'm REALLY upset and mad," a staff member wrote in an email to Wielenga. ``You told me last week 5000 (packets) a day, now 6000 today and now I have an email from Nisha also saying 6500 today. The email, believed to have been written in around May 2011, complained about a lack of staff to handle orders. ``If you had let us hire the people we needed over 4 weeks ago when we asked we would not be in this problem of backlog we are in of being behind," the email states. Another email written under Wielenga's name to an Australian team leader indicates he micromanaged elements of the business, referring to customer complaints about underweight bags. ``Our customers are paying a lot of money for our product and the presentation is of utmost importance," it reads. The documents, lodged in the confiscation proceedings, say a form of synthetic cannabis, JWH-018, was made illegal in September 2011 as part of a crackdown. Police allege from September to November 2011, Wielenga sold products with the same pharmacological effects and a similar chemical structure to the banned substance. Officers searched a property at Olsen Rd at Southport owned by a company connected to Wielenga, Subliminal Marketing Pty Ltd in October 2011. The space was allegedly being used as a distribution centre for synthetic cannabis, with police seizing 46kg of plant material that was allegedly found to have compounds substantially similar to JWH-018. An Australia Post outlet at Surfers Paradise and an apartment block were searched by police in November 2011, with parcels, synthetic cannabis, merchandise and documents seized. A preliminary police review allegedly found $563,113 in invoices were dispatched from Lightyears Ahead Ltd in Australia allegedly run by Wielenga between September 9 and October 3, 2011. A ``declaration of compliance" was allegedly signed by Wielenga, stating Kronic Black Label was manufactured on July 15, 2011 ``specifically to comply with recent changes to federal regulation" of synthetic cannabis. ``Kronic Black Label complies with all State and Federal laws and can be freely sold," the letter reads. Daniel Baptista, a senior chemist with the State Government, said in an affi- davit the synthetic cannabis allegedly had a chemical structure that could be considered ``analogues" of JWH-018. Clinical forensic medical officer Adam Griffin said the synthetic cannabis agents used in products allegedly sold by Wielenga had a ``substantially similar" effect to the illegal drug. The Crime and Misconduct Commission has successfully sought orders from the court temporarily restraining properties owned by a company connected to Wielenga. The CMC has applied for a court order that Wielenga derived $516,297 from illegal activity and the money be paid to the State Government. Wielenga was this week charged with trafficking synthetic cannabis from September to November 2011 after travelling from New Zealand voluntarily to face the charge.
