What are the key differences between dextroamphetamine and methamphetamine in terms of their effects and medical uses?

Dextroamphetamine and methamphetamine are both stimulant drugs, but they have different effects and medical uses. Dextroamphetamine is commonly used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy, while methamphetamine is not approved for medical use in the same way. Methamphetamine is more potent and has a higher potential for abuse and addiction compared to dextroamphetamine. Additionally, methamphetamine is often associated with more severe side effects and negative health consequences.
