I want to share this link with you because it has me outraged. Some Police departments, forensic labs don’t even have the proper equipment needed to detect some of the drugs like Isotonitazene that is on the rise poisoning people. This drug came into the US in 2019 so my opinion is that’s long enough to have proper testing equipment. Many homicides by poisons are not being accounted for because of this. Just not right. Here’s a link to give you more information about this.
