A website called Silk Road is a virtual marketplace that sells every drug imaginable from precursor chemicals to prescription medication.
Vendors from countries including the Netherlands, the UK, Germany and Australia advertise and sell their illicit products on the website.
Ryan West, 20, a self-confessed drug dealer, says he has made a lucrative living from buying illicit drugs via Silk Road.

"You can get anything and everything in any quantity. You can get LSD, heroin, amphetamines, cocaine and research chemicals," Mr West said.
"The drugs are hidden inside ordinary-looking parcels and envelopes, delivered direct to your mailbox."
According to Mr West buyers can leave feedback about sellers and drug quality, similar to websites like Amazon and eBay.

"It has guides on how to buy and sell, it's very clear on what to do," Mr West said.
Mr West is one of thousands of Australians who uses the website. He says he has spent over $20,000 on MDMA (ecstasy) in the past six months alone.
Like other users of the website Mr West doesn't buy the drugs using a credit card. He says he uses a popular cyber currency called Bitcoins instead.
"Bitcoins is an untraceable currency ... you just place an order, give them your address and they'll send it," Mr West said.
Mr West was recently caught by the police and sentenced to a 12 months' intensive supervision order for drug possession and dealing.
He claims he has turned over a new leaf.
Despite a steady increase in drug seizures at the Australian border Silk Road's business is still booming, turning over a reported $22 million a year in mostly illegal sales.
The website has escaped prosecution because it doesn't operate on the freely available part of the internet that most of us access every day. The website resides in a hidden part of the world wide web called the 'dark internet'.
Tech expert Seamus Byrne, editor of CNET Australia, says the area of the 'dark net' is where people can trade in goods that are completely illicit.
"Sites like Silk Road can move constantly, so it's not sitting on a normal website address where you can shut it down. It is not sitting on a normal server," Mr Byrne said.
"This is something that is built into 'highly-anonymised' technologies on the interest so that it's constantly able to hide. Essentially, it becomes almost impossible to shut it down."
While it's not illegal to access Silk Rd, it is illegal to import or attempt to import drugs from the site; penalties can range from an $825,000 fine to life imprisonment.
In a recent Parcel Post sting, the Australian Federal Police seized 140 packages containing $8 million worth of drugs. Six of those arrested were Silk Road members.
