I think all drugs should be illegal. Why have some legal and some not?

Having some drugs illegal and some legal can be seen as a way to help control the usage of certain drugs while still allowing access to them for medical or recreational purposes. Drugs that are deemed too dangerous or addictive are usually made illegal, while some drugs that are seen as more harmless are allowed to be sold legally. Additionally, laws can also change depending on where you are in the world. In some countries drugs that are considered illegal in the U.S. may be sold and purchased legally.
