I have read alot about grapefruit juice potentiating opiates because it binds with the same enzyme as opiates, but what about kratom? I have read on some kratom groups and sites that grapefruit juice works well at potentiating kratom, and in fact I have just tried it out. I kinda wanna say that I can already feel it hitting me a bit harder, but I think I will need more time to tell. I took a normal dose (1 1/2 tablespoons mixed in pudding) and within 40 minutes the effects were coming on strong. I feel more sedated than normal, but I'm not sure if the grapefruit juice made much difference. I will report back latter. Can anyone else share any experiences? Some people swear by this method.
