I have tried the following: 7.5g bali, 15g bali, 5 grams thai, 10 grams thai and 6 grams indian. Very very mild effects in all cases, the bali being a little more chilled while the thai and indian made me a little on edge. But these were REALLY mild effects, the thai was like a cup of coffee and the bali was like one or two units of alcohol. I was buying powdered kratom.
I have taken it both by mixing with boiling water and microwaving for one minute, and eating raw in yogurt.
Is it possible that I have natural high tolerance to kratom? I cant think that 15 grams would have no effect whatsoever unless someone had a ridiculously high tolerance to it?
If its useful at all, I also have quite mild effects from codeine. I dont know if its related at all.
If anyone can suggest whats going on, I would be pleased to hear about it!
