You really have no idea what you're talking about. No lives have been ruined in Thailand over Kratom except people who got put in jail over it. And red vein thai is just a type of Kratom sort of like Columbian is a type of coffee. It's not stronger or weaker. How do I know? I've used Kratom for 15 years.
There are plenty of people addicted to Kratom, you being one of them obviously.
You are echoing my point brah, certain types have different pharmacology, some have clear MAO-B inhibition like red vein as they are stimulating. Certain types also have different alkaloids which lends to the dirty pharmacology it has, clearly some strains are stronger than others. What do you mean by stronger?
Using your analogy, some coffees are stronger than others, if we are talking methylxathine content, if we are talking anti-oxidant level, it's more broad.
Your analogy is flawed unfortunately broseph... caffeine has no endogenous ligand or system, it exerts it's effects via Adenosine antagonism and phosphodiesterase inhibition. Opoids and the endorphin system are endogenous, we produce endorphins. Because we have a whole system for opiates, multiple receptors with differing effects you can have quite a difference in pain relief , euphoria etc, the mu, delta and kappa receptors act differently, oxycontin has a different response versus hydromorphone. Kratom being a plant like Cannabis, can be sedating, a mix, stimulating, last long or short etc you my friend are wrong.
I didn't check anything I wrote so if you can be so kind to double check my statements for validity it would allow me some free time.
