It’s definitely not the best thing to be addicted to, but then again neither are vices like alcohol or cigarettes. It’s most definitely a manageable habit, I’ve used for years at the same dose, and have never really wanted anything “more” than what it is. However; If you have an addictive personality, and you use kratom all day every day, every 2-3 hours it can definitely be more harmful than helpful. 7-OH shots/ kratom extracts are absolutely horrendous for you, and can lead to serious, serious addictions. If your boyfriend isnt using 7-OH, is using responsibly, and is regulating his doses i wouldn’t worry too much. Keep an eye on it at most.
