purpose of the holding is related to drug abuse. Following a decision by a prosecutor, the police may destroy the seized drugs. In Ireland, the Criminal Justice (Psychoactive Substances) Act 2010 bans substances based on their psychoactive effect, and was introduced as a catch-all to address the time lag between new substances appearing and their being banned individually. In the United Kingdom, the Psychoactive Substances Act 2016 adopts a similar approach. Some countries, Australia for e.g., have enacted generic bans but based on chemical structure rather than psychoactive effect. If a chemical fits a set of rules regarding substitutions and alterations of an already-banned drug, then it too is banned. Brazil adopted the same model as Australia, in a recent ruling from ANVISA, which is responsible to define what constitute drugs. Temporary class drug A temporary class drug is a relatively new status for controlled drugs, which has been adopted in some jurisdictions, notably New Zealand and the United Kingdom, to attempt to bring newly synthesized designer drugs under legal control. The controlled drug legislation in these jurisdictions requires drug scheduling decisions to follow an evidence-based process, where the harms of the drug are assessed and reviewed so that an appropriate legal status can be assigned. Since many designer drugs sold in recent years have had little or no published research that could help inform such a decision, they have been widely sold as "legal highs", often for months, before sufficient evidence accumulates to justify placing them on the controlled drug schedules. Common names In the UK to avoid being controlled by the Medicines Act, designer drugs such as mephedrone have been described as "plant food", despite the compounds having no history of being used for these purposes. In the US, similar descriptions ("bath salts" is the most common) have been used to describe mephedrone as well as methylone and methylenedioxypyrovalerone (MDPV). Combined with labeling that they are "not for human consumption," these descriptions are an attempt to skirt the Federal Analog Act which forbids drugs that are "substantially similar" to already classified drugs from being sold for human use. Synthetic cannabinoids are known under a variety of names including K2, Spice, Black Mamba, Bombay Blue, Genie, Zohai, Banana Cream Nuke, Krypton, and Lava Red. They are often called "synthetic marijuana," "herbal incense," or "herbal smoking blends" and often labeled "not for human consumption." List See also Controlled Substances Act
