That's pretty strange since the evidence that n-iso is used to cut meth in different places around the world is pretty easy to find. This isespecially true in Australia were people/gtoups use it to cut the majority/completely l-meth that they sell as ICE currently in Australia.
" In 2007–2008, Drug Enforcement Administration (DEA) reports have shown that a compound called
N‐isopropylbenzylamine (
n‐(1‐methylethyl)‐benzenemethanamin,
N‐ipb, Figure 1) has been used first as an adulterant or substitute for METH in seized drug samples in the United States. 13 , 14 , 15
In New Zealand, many products of ‘pure METH’ sold in the street are adulterated with at least 50% of
N‐ipb. 17 Additionally, drug dealers in China have sold
N‐ipb as fake ‘Ice’ METH in many recorded cases. Although
N‐ipb is a border controlled substance in Australia, it is not currently known as a controlled substance in other countries."
N‐Isopropylbenzylamine (N‐ipb), a chain isomer of methamphetamine (METH) with similar physical properties, has been used as a substitute for METH in seized drug samples. However, the abuse potential of N‐ipb remains unclear. Therefore, this study ...

"Over the course of the next month the origins and links between multiple consignments seized by the ABF were reviewed and found to contain border controlled substances, including eight kilograms of isopropylbenzylamine (a methamphetamine analogue) and quantities of heroin, cocaine and other drugs from various source countries"
"New Zealand’s drug checking organisations (KnowYourStuff, NZ Needle Exchange and NZ Drug Foundation) have been seeing something called n-isopropylbenzylamine (shortened to n-iso) turning up in substances that people thought were methamphetamine."
New Zealand’s drug checking organisations have been seeing something called n-isopropylbenzylamine lately. Here's what we know.

Crime gangs are deploying Breaking Bad methods and exploiting legal loopholes to mass-produce a new “imitation” meth, which is cheaper to produce but more hazardous. Australian crime gangs are importing a chemical known as “ISO” to produce a cheap and deadly imitation meth.
