The bottom line is, blunts are wasteful compared to any other method of smoking. However, blunts are also fun to smoke sometimes, especially in large social gatherings. So, if a person doesn't mind wasting their stash, who are we to criticize? I've smoked out of every possible device or preparation I can think of, and I enjoy them all. For everyday use, I stick with the vaporizer at this point, but if you want to smoke 2-5 grams at once in a blunt (as someone suggested above), go for it, and more power to you.
By the way, whoever it was who said they smoke 2-5 gram blunts everyday, what quality of weed are you getting? I would assume schwag? If not, you must have a lot of money. And if so, well, joints and blunts are about all it's good for, so keep it up.
