i've got a question about smoking it... does it matter wether its the HCL (or any other) salt? or is it necessary to have it as the free base?
edit:
you can test your substances using simple chemistry like the soluability in water, ethanol/methanol or gasoline, the boiling point etc you could also use a marquis test if you find someone who already did it so you can compare your result with what it should look like. other than that i dont know any way except for professional drug checking
