LE intel. report: NH3, security, diversion, denatu

[Chicken]

A newer LE Inteligence report on methods of denaturig, preventing theft of, as well as revention of diversion, NH3:

Under this option, a chemical or compound added to anhydrous ammonia would be able
to accomplish one of five different outcomes:
· Neutralize ability of NH3 as a solvent or catalyst in process
· Prevent meth from providing euphoric rush (desired effect)
· Results in an unusable (bad) product
· Makes meth user sick
· Results in combustion as part of production format

Sulfur addition? That would form large amounts of H2S during reduction... They rather kill meth cooks deliberately, than bothering to find a safe additive?
