Question Ephedrine vs Methamphetamine

[narabreakingbad]

Hi guys!

Im little confused. If I understand correctly ephedrine is a naturally occurring alkaloid, yet meth is man made, synthetic substance.

So how does this work?

Please someone clarify this for me.

Meth does not occur in nature, it is man made using different routes from various precursors including ephedrine.

It's like ephedrine is crude oil that occurs naturally, and meth is plastics that people make from crude oil.

So why there are no ephedrine listings?
