How much does an oz smell?

Its not gonna stink that much, just double bag it if you're paranoid about it..

It all depends on what kind of cannabis it is too. I have had ounces before that you couldn't smell single bagged, in an open room, but I've also had like 1/4's that totally reeked.

Some weede smells more than other kinds of weed. Hopefully you get the kind of that doesn't smell that much.

If would get 2 jars if I was you. Get a bigger jar that can hold an oz and has a rubber seal, then get another one for taking around with you. I use a strait amber jar that I found at a cooking store. It is about 3" wide and high and can hold a 1/4 inside a plastic bag.

I came across this while looking for a picture of a good jar.
