South Australia Police say they have seized thousands of fake Xanax tablets from a Craigburn Farm home as part of an ongoing investigation into drug trafficking in the southern suburbs.
Police searched the home in the prestigious Adelaide Hills suburb on Friday afternoon and arrested a 21-year-old man at the address.
It will be alleged officers found approximately 3,000 fake Xanax tablets along with various other prescription and imitation medications and a trafficable quantity of cannabis.
Xanax is a brand of prescription medication commonly used to treat anxiety and panic disorders.
Police also allege they found approximately 1 litre of liquid heroin, which is also known as "heroin slushie" and about $10,800 in cash and drug trafficking paraphernalia.
The man has been bailed to appear in the Christies Beach Magistrates Court in February on drug possession and trafficking charges.
Police said more charges could be laid following further forensic analysis of the seized items.
In a statement, police warned the public about the dangers of taking prescription medication not prescribed by a doctor.
"They may contain toxic or dangerous substances and are manufactured without any standards or quality control, often in unsanitary conditions in backyard laboratories," the statement reads.
"People involved in drug trafficking have no care for those that they harm through illicit drugs."
Investigations are ongoing.
