once had an idea to mess around with this subject.
He took a 30mg IR adderall
and broke it down. Placed it on a spoon with some water in it. He proceeded to heat it but not boil it. He was not sure if the amphetamines were heat resistant or not.
Moving the spoon around in a circle, the filler seemed to dry faster and on the outside of the spoon. May Swim add that he used a large spoon at that.
After drying, what was left was less amount than a full pill. It also was a darker orange and looked like it formed to crystals.
Turned out very good for snorting
. Had more of a kick to it but would not recommend any IV use though. The experiment took a little bit. This was some years ago and details are not fresh but it was more concentrated for sure.
