So, for 4/20 I purchased a small acrylic bong that hits very well, much better than my old one. It gives great hits, however I've noticed something.
If I fill it enough with smoke, it brings this cool, white smoke that hits well. However, if I really try to get a HUGE hit, the smoke turns a slightly creamy, yellow-tinted color and it makes me cough a lot worse.
My question here is, what causes the smoke to turn slightly yellow? Is it from just smoking mids and not anything better, accidentally smoking stems (I don't normally take out but the biggest stems), or is it from another factor? Thanks in advance for any help
