Lightbulb Vape

My lightbulb vape has lasted me countless sessions and bowls... i was wondering thou after a long session why the hell my throat gets tore up so much more than just a bong hit or somethign like that... also it tastes funky.. i really dont know why i didnt address this earlier.. probably because i forgot . oh well. it still is amazing at gettin me high even thou i get 3-4 crushing hits and thats it.. but i always pack it light becuase they go straight to my head.. err im rambling

oh yea i forgot to ask is the reefer left over from a vape still good enough to roll a J and enjoy later or is all the thc and stuff gone?

You can use the stuff left over to cook with, I'm not sure if you can smoke it again. I don't think you can smoke it, but I could be wrong.
