sorry if stuff like this has been asked but I am unable to find it in search.
How would one know if sodium hydroxide has leached into the non-polar solvent and ended up in your finished product, even after a re-crystalization? what are the chances of this? what would your symptoms be like? My spice didnt leave anything behind on vaporization, wasnt harsh at all but it did feel like it coated my throat a bit. a little heaviness in breathing still today, although I was smoking pot lastnight for the first time in weeks and smoked some cigarettes. Spice is super super white, and fluffy-ish.

What are the effects of spice vaped in a bulb pipe that still has naphtha on it? I dont think this is the case with mine, I just want to know the possibilities and effects. Experience was great on 20 mg, I just feel like i can still feel the hit from lastnight, it doesnt hurt or anything, it just feels a bit like conjestion.

Thanks
