Eh, I doubt it to be honest. I think it actually is a legitimately dangerous drug that happens to be very visible to the public due to its strength and seeming favour amongst the homeless. Its causing a whole bunch of overdoses which takes up the time of the healthcare system and it has a strong link with public nuisance, both in regards to the effects of the drug and the type of people it attracts in the first place. Plus its new and sexy to the media compared to traditional drugs of abuse, when you add it all up it isn't that surprising that its making headlines.
