I have been taking Kratom powder for nearly 10 years daily. Occasionally I will take a break from it, and to be honest, I've never had any issues as far as withdrawal symptoms. It is not an opioid. It is a mu opioid antagonist. Much research has proven that this does not activate the pathway that suppresses breathing. 

Nearly every single reported death associated with kratom we're due to co-substances. Usually strong substances such as cocaine, methamphetamine, heroin and others. Kratom alone does not cause death or medical problems in general any more than coffee would. In fact, Kratom is related to the coffee plant. 

In fact, Tylenol, an FDA approved medication, causes liver failure and ultimately the death of nearly 500 people a year in the US alone.

I urge you to disregard the comments stating that this is a medication, It is not a medication but an herbal supplement used by many to help with chronic pain conditions. It's efficacy Is life-changing. I know that it has changed my life to be a productive human, maintain a job, and helped quell my social anxiety without the need for heavy pharmaceuticals.
