Tasmania Police are warning of the dangers of using synthetic drugs designed to replicate the effects of cannabis.
These drugs are being sold under the brand names of Marley, Malibu, Green Lantern, White Devil and WRX, according to Drug Investigation Services.
Police said that despite being sold through various business outlets across the state, the possession and use of these drugs is illegal in Tasmania.
A quantity of the drugs have been seized by police from a number of retail premises, and investigations are continuing.
Police say that a number of users have been hospitalised after taking the synthetic drugs, with side effects including uncontrollable drooling, agitation, delusional behaviour, loss of balance, an inability to speak and in some cases seizures.
