I don't know. I have heard of people selling coke laced nugs as both snowcap and white widdow, and those are also real strains. However, I have only ever heard of cocoa puffs meaning coke and bud, and to me "cocoa puff" is the only correct term for coke and bud in the same bag. The best way to tell is to look at the nugs. Does it look like someone shook a bunch of cocaine into them? Is your dealer the kind of sketch ball who would sell laced weed? Most dealers will just sell coke and weed and let you make your cocoa puffs yourself because they want to be able to sell plain weed and plain coke for people who don't like them mixed together. How much did you pay for it? Did it seem like you were paying for both weed and coke, because if he is just charging you weed prices for weed and cocaine then he's losing money, and dealers like their big screen plasma TVs. Laced bud is rare, but that's not to say it doesn't exist. Be careful, buy from people who you trust at least as far as you can spit, check your weed before you smoke it. If you rub the tip of your finger on a nug and powder comes off, it is probably worth taking a close look at before smoking. Looking at bud under a magnifying glass makes it real easy to tell trichromes from powder. If you still aren't sure rub some powder off and taste it. Does it taste like weed?
