EMT Chapter 26-MCIT-F3-2216 | The Toxicology Takeover:  This course is built for the modern EMT facing a drug landscape that no longer follows the old rules. Today’s overdoses are rarely simple, often layered, and frequently deceptive-requiring structured thinking under pressure than reflex treatment. 

The lessons covered are

• Lesson 1:  The New Drug Landscape
• Lesson 2:  The Alpha-2 Invasion
• Lesson 3:  The Chameleon Drugs
• Lesson 4:  The New Assessment Framework, and,
• Lesson 5:  Putting It All to Work

Excerpt from EMT Chapter 26-MCIT-F3-2216 | The Toxicology Takeover

Morphine is at 1. Heroin turns it up to 2. Fentanyl cranks it to 100, which is why it became so dangerous so fast. But here is what a lot of providers do not realize yet: we have now moved past fentanyl as the ceiling. Nightazeenz, drugs like protonitazene and ee-toe-nyetahzeen, are 10 to 40 times more potent than fentanyl. Kar-FEN-tuh-nil, which was developed to sedate elephants, clocks in at roughly 10,000 times morphine.

Now, you might be thinking – that seems almost unreal. How do you even dose something like that? The answer is: you barely do, and that is exactly the problem. The margin between a dose that gets someone high and a dose that kills them is essentially invisible. Street users have no idea what they are getting, and neither do you when you arrive on scene.

The other critical concept here is binding affinity. These drugs do not just hit harder – they grip the receptor tighter than Naloxone does. That is why standard doses of Narcan fail on some of these calls. We will return to that idea repeatedly throughout this course, because it changes how you think about dosing and transport decisions.
