Wait they are adding MCPP to Cocaine? Wait for what? Wouldn't it be easier to cut it with something else? This is really confusing.
While I don't doubt that the drug producers would cut their products for extra profits, this article reads like a propaganda piece by the government. While I haven't done MCPP by itself and I hate getting piped, I would hardly call piperzines toxic. I even find a small dose of BZP by itself to be decent if you what you are taking and are not expecting MDMA like effects. I don't know, perhaps MCPP is different.
