Do we have cannabinoid receptors because of ancient use of marijuana?
I have heard that we have cannabinoid receptors but I was wondering why

The human body naturally produces and uses chemicals that are similar to cannabis (endocanabinoids).
Marijuana is a similar compound that tricks the body into using it instead of the real stuff.

Humans manufacture a range or cannabinoid-like molecules for emergency pain management.
This level of pain management is short-lived and is used to suppress the pain while the person removes themself from danger. I’m sure you can appreciate that we’re talking about having limbs ripped-off by savage animals, or generally things that pose a high risk of death.
At those situations, the body goes more or less into automatic-drive. The fight-or-flight response activates. The heart rate and blood pressure rises to oxygenate muscles for rapid response. People have reported unbelievable (but temporary) increases in strength. Activities may appear to go into slow-motion as the person seeks to remove themselves or their child from danger
As the situation recedes (and assuming we are still alive) the realisation of major injury may cause symptoms of shock – blood pressure and heart rate may bottom out, feelings of dizzyness/light-headedness/weakness/nausea may appear, uncontrollable sweating, shivering or shaking, etc – at that point hopefully medical aid has been called.
