Similar story here - it undoubtedly has improved my quality of life. I too use it as a kind of "herbal adderall", and only use plain leaf powder from a trusted vendor with many years in the business who provides testing data and tests every single incoming batch for contaminants.

It has addictive qualities, sure, but the safety profile is similar to coffee or cannabis. The benefits, for me at least, far outweigh any risks, which are minimal to begin with.
