Warning to the general public: There are psychoactive substances which can be mistaken as cannabis, cocaine or methamphetamine as noted in the report of the AFP.

What is more alarming is the fact that such substances, as noted by the same source, are being marketed as legal alternatives.

"Synthetic drugs are dangerous substances that can kill and should not be available for sale," Assistant Treasurer David Bradbury reminded the public in a press release in light of the federal government's order to ban the national supply and sale of 19 synthetic drugs that closely resemble illegal substances for 120 days.

The ban took effect in South Australia last June 13. The South Australian territory consists of places such as Adelaide, Mount Gambier, Whyalla, Gawler, and Murray Bridge among others.

Here is a list of the drugs on ban, as provided by adelaidenow.com:

White Revolver

Ash Inferno

Kyote

K2

Black Widow

Iceblaze

Montana Madness

Iblaze

Galaxy Ultra Nova

Skunk

Kronic

Vortex Inferno

Herbal Incense

Buddha Express Black Label

Iblaze Tropic Thunder

Sharman

Slappa

King Karma

Circus Deluxe

According to the press release, the ban is meant to allow the health and law enforcement agencies to update the current laws on synthetic drugs. It is important to note that such substances have been legally sold and used because certain State and Territories have yet to adopt the Therapeutic Goods Administrations' poisons standard.

"The synthetic drugs market is fast-moving and suppliers have shown they are willing to change brand names and packaging to get around bans made under consumer laws, "Bradbury further warned.

He also urged the State and Territory Governments to "conduct an urgent review of their drug laws to make sure that these synthetic drugs are not falling through the cracks."

Synthetic drugs were dragged to the spotlight earlier this month due to the death of Henry Kwan, a teenager from Sydney. The Daily Telegraph reported that Kwan was allegedly under the influence of a drug that closely resembled LSD when he decided to take his own life by jumping off the balcony of their home in Killara.

The boy "believed he could fly", as his father, Stephen Kwan, told the reporters.
