The Liberal Democratic Party and ruling coalition ally Komeito have drawn up a draft amendment to the Pharmaceutical Affairs Law that would allow sales bans on quasi-legal drug products to be applied nationwide rather than just to a single store, according to sources close to the ruling camp.

Currently, when a store is ordered by inspectors to suspend sales of products containing substances designated by the health ministry as "dangerous drugs," the order applies only to that particular retailer. The amendment proposed would help end that piecemeal approach.

The draft also proposes widening the definition of products that can be pulled from sale to include not just drugs suspected of being designated substances, but also any other product suspected of having equal or greater hallucinogenic or stimulatory effects, the sources said Saturday.
