explain what distinguishes medicines from drugs and why medicines are drugs but not all are medicines

The difference between drugs and medicines is pretty basic, but a lot of people often interchange them. The main thing that differentiates them are their legality and society's perception of them. Both are used for the treatment or cure of diseases, but drugs have a more stimulating and addictive effect to the body than medicine. On the other hand, medicines generally don't have such effects.

Explanation:

I'm not an expert, but medicine's are drugs, created to help people, in certain ways, such as Adderall helping with ADHD or Elderberry. But drugs that aren't medicine are like cocaine that might've been used for medicinal uses back in the day, but now is just used for personal use, such as weed, it can be considered medicinal but it's used more for pleasure than to help a illness
