The ephedrine (or pseudoephedrine) synthesis is a one step using phosphorus/iodine reduction directly to methamphetamine. It’s simple and clean in that only an acid base extraction is required, and only one set of NP solvents.
All these others syntheses with multiple steps up the chances of weird toxic solvents or contaminants creeping in. I think it’s a contaminant issue that’s exacerbated by the drug use.
The government should just regulate it, control purity and production and let people access small amounts for recreation/performance. It’s not an evil drug per se - long history before it was criminalized. Plus that would neuter the cartels and protect people’s health more than pushing it underground.
