Is Methamphetamine synthetic or naturally occurring?

Question

I cannot find information on this. And no, this is NOT for personal information, lol, I need help finding the answer for my health class. I've done research, but I am unable to come across the answer. Thanks in advance. :D

Answer 1

Both.

Methamphetamine occurs naturally in Acacia berlandieri and possibly Acacia rigidula, trees which grow in west Texas. Acacia trees contain numerous other psychoactive compounds (ex.amphetamine, mescaline, nicotine, DMT) but scientific papers specifically mentioning the presence of methamphetamine did not exist until 1997 and 1998.

Methamphetamine is most structurally similar to methcathinone and amphetamine. When illicitly produced, it is commonly made by the reduction of ephedrine or pseudoephedrine. Most of the necessary chemicals are readily available in household products or over-the-counter cold or allergy medicines. Synthesis is relatively simple, but entails risk with flammable and corrosive chemicals, particularly the solvents used in extraction and purification. Clandestine production is therefore often discovered by fires and explosions caused by the improper handling of volatile or flammable solvents.

Answer 2

Since it cannot be mined or harvested directly from a plant or animal, it is made (synthesized).  

And I stand corrected, if it occurs in a tree, it is naturally occurring, good source, I learned something new.
