New Psychoactive Substances (NPS), also known as ‘synthetic drugs’ also known as synthetic cathinones or ‘legal highs’ are chemicals that are made to act in a similar way to drugs like cannabis, ecstasy, cocaine or methamphetamine.

More than 1100 NPS have been detected in unregulated drug markets in Australia and around the world, this includes close to about 100 novel opioids, like fentanyl.

They come in different forms including:

a) Powders, but also exist in small, chunky crystals, capsules and less commonly as tablets
b) Synthetic cannabis (synthetic chemicals that have been added to herbal or plant material).

Although called ‘new’ some have been around for decades and are often sold as incense, bath salts, plant food or wrongly marketed as safer or legal alternatives to other drugs.
