I was a bit iffy how to vote, but I marked down "Cocaine".
The reasons I was not sure, is that while I prefer the cocaine high overall, the amphetamine high is certainly more stimulating, imho, keeps me up longer and makes me more alert.
The other reason is that while I´ve probably just had amphetamine, I have been told that I was taking "flower-speed" before, a local term for a smelly type of speed (sometimes brownish) that has noticably different effects from the white powdery stuff you got most of the time.
Basically it was still a stimulant and felt much like normal speed, but quite a bit more euphoric and usually resulted in a much more fucked up evening. I prefered it, and if it was meth, then I love meth
However, I am inclined to believe it was simply amphetamine sulfate from a better source, perhaps more clumsily made but far more pure. For one thing, it was in Europe, where meth is scarce. I would think there would be a bigger premium on meth, this stuff was only slightly more expensive than regular speed. And I´d think that more people would want it instead of normal speed, which was not the case, many people blamed it for "going over the top".
To make an overly long post short, I like coke and all kinds of speed (whatever it was), but coke wins
