I’ve been using kratom every day for at least 10 years now. I have chronic pain and use it so I don’t have to use oxy. I get regular health checks and I haven’t had any problems with it. That being said, there are extracts, I believe those are more dangerous. If you just take the leaf, you’ll throw up before you overdose. I also think mixing it with other drugs is not a good idea. Everyone is different though, what applies to me will not apply to everyone else.
