Under the changes, people caught possessing the three types of N-bomb can be jailed for three months or fined $500. Those caught dealing can be sent to prison for 14 years.

Other similar drugs would be caught under legislation as Class C drugs, while anti-psychoactive substance laws were also still in force.
