I haven’t tried opium or heroin. But I’ve taken a fair bit of kratom. But now it’s illegal in my country.

It’s effect is pretty mild compared to opiates. Take a light dose, it gives you energy and elevates your mood. A heavier dose makes you relaxed and mildly euphoric.

To me it wasn’t very addictive other than I used it to work longer hours when renovating my house. Also good when you do heavy labor since it also have pain relieving effects. So I took it more or less daily for about two months, then I quit. The first days I noticed my mood was a little dampened but nothing more than that.

I only tried it in natural powdered form. But in some countries there are extracts and products that are more potent, which probably is worse to quit.

Also hard, at least for me to overdo it since if I take to much I get nauseous. But maybe that’s just me.

Overall I find it a very useful and practical drug.
