some how on this last batch I hit some off the ti. It was like a taffy but I noticed a taste that was not good at all. Afterwards I proceeded to remove the additional solvent it turned to budder on more heating and churning. I tried some this morning and it tasted funky but there are definitely no bubbles. I've been doing this for a while now and was enjoying with no probs before but still aware of the possibility of residues. now I am concerned about these. We should have access to laboratory grade extracts. My lungs are feeling terrible. I'm seriously worried about the health risk here. I think I'm going to have to quit consuming bho I'm kind of in a panic. I am usually healthy I can get on a treadmill and run a couple miles even though I haven't switched to vaporizing with my herbs yet. this is really impairing me. For those thinking of making bho I'd wouldn't reccommend it too much stress. It my fault for sampling it too soon. I need your advice on how to medicate for optimum health. I think I want to phase out bho. Even though now I have the technique mastered. Am I gonna be okay ?I can feel my lungs are no bueno I'm worried about the psychological effects of all this. Thanks for the support.
