Just tighter controls on ephedrine and pseudoephedrine. Any dumbass can make it in the bathroom easily with homemade lab equipment using ephedrine, so a lot of law and law enforcement crackdowns have centered on that.
I haven’t seen the show in a long time and never finished it, but from what I remember, later in the show they ditch both methods and move on to methylamine. Going that route would also allow production of isolated d-methamphetamine.
Fun fact: This is explained in Breaking Bad. … not the chemical breakdown (IIRC, so thanks for that!) but the difference in production.
Wonder if it made any impact on the popularity or still just tighter controls on ephedrine.
