I recommend you compare the wikipedia pages of both amphetamine and methamphetamine. Meth is directly neurotoxic, even at "normal" doses of 10mg, while amphetamine is actually neuroprotective until you use really big doses. Vyvanse is basically amphetamine hooked to a protein that has to be metabolized before it has psychological effects, so lowers its abuse potential. I'm 100% in favor of amphetamine legalization, but we've got to be smart about it and not allow toxic forms of it to be available. Pure meth should not be legal, nor should pure fentanyl or cocaine(methylphenidate would be a good alternative with a better safety profile)
