Vaporizer question

[Bigg420]

Picked one up the other day and had a few questions.

Since the test is diffrent how do I know when it is cashed?

what kind of vape do u have. my buddy has the volcano and the bud is usually a brownish color for dro, for reg's its a little tougher. just look for darker color like Ribbit said, and if theres no vapor coming out when your filling up then u kno its ca$hed

I think you can also kinda taste it when it's done.
