Thank God!!! You are the first person who has said something I can relate to. I have been FREAKED! I just took 2 garcinogea supplement capsules, and belched a few minutes later & out came a cloud of "smoke". I have bronchitis and someone I know just died of lung disease, so yes, my imagination was raging for a good 2 minutes! Now I say to us both, not to worry. Strangely, we expelled powder from our capsules. Crazy!
