There are hopes the Government's latest crackdown on the misuse of nitrous oxide gets the message through to retailers.  People inhaling the gas to get high is becoming a serious public health concern. Imports of the gas will soon need approval from the Director-General of Health, while large canisters, also known as nangs, will automatically be classified as psychoactive substances.
