In New Zealand, the legality of "party pills" (recreational drugs) has undergone several changes. Around 2012, the New Zealand government enacted a new law requiring manufacturers and distributors of party pills and synthetic cannabis to test and prove the safety of these products before they could be legally sold. This meant that all new psychoactive substances (including so-called "legal highs") had to go through a rigorous review process to ensure they did not pose significant risks to public health.
Prior to this, some party pills containing substances like benzylpiperazine (BZP) were legal and became very popular in the early 2000s. However, due to safety concerns, such drugs were eventually banned.
