The DEA managed to crack the code of several emoji combinations and their corresponding drug. For instance, a pill emoji, chocolate emoji, and bus emoji are all innocuous on their own but together are a reference to Xanax. While a chocolate chip cookie emoji refers to a large batch of whatever drug is being bought.

While the DEA says that the use of these emojis alone doesn’t indicate illegal activity, they said a change in behavior in conjunction with this coded language can point to something worse.
