Could human-synthesized chemicals like LSD or Methamphetamine theoretically also occur in nature or are there structures/properties/materials irreplaceable?

Question

Full disclosure I’m on a journey back from Meth addiction. I’ve just always found it interesting how people will smoke Marijuana or eat Mushrooms but will refuse to do a line of coke or a tab of Acid. The logic is always that some substances occur naturally and are therefore fine for human consumption.

But wouldn’t human-made compounds and chemicals also eventually occur in nature given enough time and the right environment? Or are these chemicals 100% unnatural?

Answer 1

For me it has nothing to do with natural or not, it’s purely based on how bad the substance has potential to be. It’s very easy to OD on many synthesized drugs, and even some non-synthesized drugs. Marijuana is for all intents and purposes, impossible to OD from.
