Editorial: Dangers of legal high' real

It's a worrying sign when the maker of a particular substance issues a warning over its use.
Such has been the case with JWH 018, used to make synthetic cannabis, which is available in various guises and under different brand names including Kronic. The creator of JWH 018, Emeritus Professor John Huffman, of South Carolina, has reportedly said its use could lead to serious psychological problems and it was not known if they were irreversible.
This is a serious admission that must be followed through by lawmakers.
The emergence of Kronic and other similar products on to the market has been noted; local dairies report they are selling it regularly and in increasing quantities. That in itself is a cause for concern. This product is on shelves next to everyday products, such as confectionary, which might appeal to young people.
Aside from the R18 markers and the individual decision of various dairy owners to not stock it, what is to stop young people being exposed to this legal substitute for what is considered to be a "gateway" drug that can lead to problems including dependency and crime?
Already Whanganui Police report having to deal with one person who was under the influence. How are they to monitor drivers who may be under the influence, or discern when people are using the legal option or actual cannabis?
What we have seen so far may just be the beginning, unless something is done sooner than later.
The Government is to fast-track legislation to make synthetic cannabis a restricted substance by mid-August.
The Law Commission has indicated it believes total prohibition a last resort, and "appropriately regulating these substances may be more effective at minimising drug-related harm than prohibiting them altogether".
Whatever our lawmakers decide, they need to act quickly.
