As I mentioned in the comments of a previous report on these Green Ghosts my impression was a medium amount of MDxx. There might have been some amphetamine added as I didn't sleep for eight hours after taking it & I want to mention the hard come down two days after taking it. I've added a picture of the Marquis Test I performed on it where I already mentioned (in a comment of a previous report) that it had a fast dark reaction with fizzing bubbles but I didn't notice any orange colour from result. Maybe there are different batches as in the previous reports have reported slow reaction with orange traces.
Other than the hard come down I personally don't think there is any reason to give out a warning here but again I'm saying that there might be different batches. I'm only talking about the pill I came across. I also heard that there are Yellow similar Ghost Pills.
