People always complaining about burning it,understandable yes I have seen some people literally sit a jet lighter directly on puddle and inhale for roughly 10 seconds and it goes completely black like syrup,my girl if she sees the slightest brown tinge whether it be from her or someone else she will literally either pick at it for half hour saying there is a contaminate in there or she will scrap it completely out and save for hotrock or hotrail,anyway me personally I enjoy 2 secs on 2 secs off with jet lighter and keep repeating until out of breathe,still tastes fine and doesn’t turn to syrup,moral of the story is if you see someone pull a jet lighter out don’t sit there and stare directly at them in disgust or bad mouth them because of a slight brown tinge,have fun with it and enjoy the company while you have it
