What is this substance, and how they make it?

[Toomuchname]

I see that nowadays there are a lot of people sell and use stuff which is called “Ice”, but it isn’t methamphetamine, but something other. They can smoke it on a foil(it becomes a yellowish liquid, when heating, and they can smoke it totally without any residue on the foil), or they can just snort it.

Attached an image how it looks like

My question is, what is this substance exactly?
And how people make it?

It is difficult to determine a synthetic substance of white color from the photo. All I see is that it's most likely hydrochloride. Describe the effects and dosages, then I will be able to answer your question more accurately

Methcathinone?

I swear this is sugar with a little lactose and little taurine, for the kick also a big amount of caffeine, 100%!
