1. This stuff is described as "synthetic cocaine," so it's not "a new form of cocaine" at all, it's a synthetic drug.
2. Any powdery substance can be put in prescription pill capsules, including real cocaine, which can also be diluted in liquids, so this stuff is not easier to conceal or a "dream for narcotics smugglers."
3. I would be greatly surprised if Colombia, where they have real cocaine labs, is producing ersatz cocaine. I dunno, maybe there'sa bored chemist somewhere down there, but it seems unlikely.
More likely, H2CB is just another new synthetic drug, like the "bath salts" drugs, some of which have cocaine-like effects. Perhaps some Colombian party animals brought some back with them from Europe.
