Freebase speed
Freebase speed is freebase amphetamine or freebase Ethylamphetamine. Amphetamine and Ethylamphetamine usually comes in solid HCl salt form. But freebase amphetamine and Ethylamphetamine is a liquid. You can smoke it or inhale the vapors. You can't mix freebase speed with water and drink it and you can't snort it. You would need speed HCl.
I turned speed HCl into freebase speed and then smoked it. It was awesome!
