Australians are keen users of drug meow meow. Experts have warned that the drug has an adverse impact on the brain, which could ultimately lead to memory loss. They have shown concern over the drug being so famous.

University of Sydney researcher Craig Motbey asserted that the people soon become obsessive about the commonly known drug mephedrone, thus causing them to spree on excessive dosage of the drug in short intervals.

He said, "Combined with the fact mephedrone is skyrocketing in popularity worldwide, with Australia following that trend, our finding that high doses can cause ongoing cognitive impairment spells a significant risk for users".

Study conducted by the university researchers is the first one to emerge with evidences, which reveal the ill-effects of the drug causing a long-term damage.

The study aimed at acknowledging the impact of the drug on brain of the rat. Rats were divided into two groups. Both the groups were subjected to the drug daily. However, in case of one group, the effects were analyzed after 10 days and in case of the other it was done after several weeks.

The study, published in the Public Library of Science Journal (PLOS One), emphasized that high dose of the drug led to memory loss, even when rats were not subjected to the drug for five weeks.
