K-Pop is a variant of Ecstasy, which also combines certain features of Adderall. It was created by Sandra June Jang, a high school chemistry teacher who supplemented her income by cooking drugs for the Korean Power gang.
It is a great high, making the skin of the user feel like it is being stroked by chinchilla fur. June was killed and the Korean Power gang was put out of business, at least temporarily – the head of the gang has a copy of her recipe, and when he finally gets out of prison, he plans to go back to dealing K-Pop right across Los Angeles.
