Methamphetamine is not a substitution for amphetamine. A substitution refers to the replacement of one atom or group of atoms in a molecule with another atom or group of atoms. A derivative, on the other hand, refers to a molecule that is derived from another molecule by modifying its molecular structure. In the case of amphetamine and methamphetamine, methamphetamine is derived from amphetamine by adding a methyl group (-CH3) to the amphetamine molecule, which modifies its molecular structure. Amphetamines and methamphetamine are closely related drugs, as methamphetamine is a type of amphetamine. They both work in a similar way by increasing the release and blocking the reuptake of certain neurotransmitters, such as dopamine, norepinephrine, and serotonin, in the brain. As a result, they both have similar effect. All you're doing is microdosing a terrible drug and calling it treatment. Addicts defend this, not logical healthy people.
