Not sure if you're joking, but he's suggesting that if bulk pseudoephedrine were still available, cartel meth wouldn't have 99% of the market like it does today.
Because yeah, your neighborhood dealer would make his own meth and would probably have lots of Sudafed.
Are you suggesting my neighborhood friendly drug dealer could hook me up with some real sudafed? Might be nicer than trying to get it from the pharmacy when I need it.
