Seeing vapor.

[Relics]

I Have learned you don't necessarily have to be exhaling visible vapor to be recieving vapor.

So how do you know when it's cashed.

you feel it and taste it brah

and you can see that your weed has turn brownish.

Also, use a lamp, black background, and exhale under or above the light, you should see something.

A keychain LED torch is also a very handy thing to have to check for vapour, especially after dark.
