Phenazepam

Although phenazepam is currently not controlled, sale for human use remains illegal in the United States. Suppliers attempt to circumvent this regulation by placing a "Not for human use" disclaimer on the product's label. Individual states in the United States often ban these analog drugs by name as they appear. Since 2012, Louisiana has classified phenazepam as a controlled dangerous substance. This ban affects several products, some of which were sold at retail stores under the guise of air freshener or similar, containing phenazepam yet claiming not to be for human use. This legislation was introduced after one such product, branded as "Zannie" and marketed as an air freshener rapidly gained publicity as the subject of numerous media reports, attracting the attention of officials. The ensuing investigation effort, led by Senator Fred Mills and Louisiana Poison Center Director Mark Ryan, positively identified the active ingredient of "Zannie" as phenazepam. According to Ryan, chemical analysis identified the active ingredient as "100 percent phenazepam". Paul Halverson, director and state health officer for the Arkansas Department of Health, approved an emergency rule to ban the sale and distribution of phenazepam shortly after the Louisiana ban. Alabama made Phenazepam a schedule I substance on March 18th, 2014.

The UK home office banned importation of phenazepam on Friday 22 July 2011 while it drafted legislation, released in January 2012 to become law at the end of March 2012. The bill was quashed following advice from the ACMD as it included two non-abusable steroids. There was a new discussion about its fate on April 23, 2012, where it was decided that the bill would be rewritten and phenazepam would still be banned. It was eventually banned on June 13, 2012 as a class C, schedule II drug.
