First off, you are correct and I should of clarified further - sorry for making that confusing.
Specifically in terms of “synthetic drugs,” thats where the molecular structure is changed (they are NOT the same as the “natural molecules.”)
The term synthetic is what matters - not that its an organic molecule.
Synthesis does not necessarily make something synthetic on a 1:1 in reference to “drugs;” or even other substances for that matter, and I’ll explain why below:
You are correct that you can absolutely create synthetic molecules (without a molecular change from what is naturally occurring) solely by using chemicals (in doing so, it’s then considered chemically synthetic). The big and most important difference is where is it derived from.
If it’s derived from the same materials where it’s naturally occurring (with our without chemicals, but not solely derived from chemical), then its technically not a synthetic drug, and arguably not synthetic at all by definition - with or without synthesis.
Based on what you just called out regarding “made from another molecule or molecules intentionally,” lets look at another set of molecules for reference:
THCa and Delta 9 THC. These are two different molecules. You are synthesizing when (by way of “degradation” through applied heat, and by definition of synthesis - degradation is technically a means of synthesis) processing THCa to Delta 9 THC. Thus, if they passed any law and set any precedent to this, Delta 9 would subsequently be “synthetic” as well.
Hopefully the players pushing against this can make sound arguments along these lines. Furthermore, there are tons of examples they can pull from outside of cannabis/hemp to reference.
A precedent like this would do so much damage to industries outside of cannabis/hemp, such as food, cosmetics, etc. The DEA is playing a dangerous game going this route, and I don’t know if they even realize the implications.
