I've found that chi dope has had a different kind of wd. You can usually tell when there are benzos present though. I know I can. Its a different high. Idk. I just talked to the guy who gave them to us. He's a friend, actually. Came right over to check on us and talk. He got right on it. I advised him to contact whoever he sold anything outta that batch to for their sake and his. He doesn't mix it up either so he's looking into that too. Hey, if i can save someone from going thru what I did, and my hubby today, it's worth the effort to me.
