Theres 2 reasons the blunt will be harsh....

The blunt wrap ... some blunt wraps produce more of a harsh taste, i try to avoid these because if you spend the extra 30 cents or so... you can get something that tastes better, and allows you to take bigger hits without feeling like death is upon you.

The weed - Some weeds are harsher than others... it doesn't mean the weed is bad, if i remember right... AK47 is the best i can get, and the harshest i've smoked.

Blunts are cool if your chillin with friends not at your house, or you don't have a bong. But i prefer bongs and pipes... but i like to chill in a circle and smoke a blunt with my friends also, every now and then.
