When I first started taking Kpin it did make me a little high like a slight euphoria, but I have been taking them so long it never happens no more. As for addiction, the potential is there, for me it is not an addiction per se, more of a dependency. Like if I miss several days dosage then I will feel withdrawal effects, which are no fun. Withdrawal for me consists of racing thoughts mainly, which would make sense as Kpin is really calming in its effects.
