What is considered a crime regarding prescription drugs?

Both actions described are indeed considered crimes regarding prescription drugs. Giving a prescription drug to a friend is illegal because prescription medications are meant to be taken only by the individual for whom they were prescribed, due to variability in individual health needs and potential side effects. When someone transfers their medication to another person, it bypasses medical oversight and could lead to misuse or adverse reactions.

Additionally, taking a prescription drug that is prescribed to someone else is also illegal. This practice can be dangerous, as medications are tailored to specific health conditions and dosages appropriate for the prescribed patient. Misuse of another person's medication can lead to harmful health consequences and is often prosecuted under drug misuse or abuse statutes.

Thus, both scenarios fit the definition of a crime concerning prescription drugs, confirming the answer that both actions are illegal.
