Everyone is saying what you should be doing, but not really answering your question.

I personally don't smoke blunts often because I have a nice clean piece to smoke with, but blunts can be fun to smoke, and convenient in certain occasions as well, I suppose. :jointsmile:

I've never had a problem when I leave a fraction of the blunt to smoke later. Although I would imagine that if you leave it out for too long your product may dry out some.

Just smoke however much you can and seal it up air-tight somewhere. That would probably be your best bet, if you must smoke blunts.
