The government announced on July 21st 2011 that the research chemical phenazepam will be controlled as a Class C drug. This gives the UK Border Agency the power to seize and destroy shipments of phenazepam.

This is just another addition to the on going research chemical bans being passed in many countries. Mephedrone has been been illegal in the United Kingdom for a while now; however, the United States has just recently invoked a ban on the substance which will begin in a few weeks.
