This one summer we burned up so many blunts being dumbasses and smoking them with fans blowing right at our faces. Smoking out the gods and burning down blunt after blunt.
Shit would be gone in 5 minutes.
I think it is more about the number of hits you can take than the time it burns which is important. I think that has more to do with the cure and the grind and the tightness. I don't like it when it seems like I'm racing against the clock to smoke my blunt so a long burn is important, sure, but the length of time that blunt exists is more dependent upon the size of the circle. The more hits you get out of the thing, the longer it'll last... So I guess same difference.
Another thing I hate is when someone rolls a loose blunt and it starts to run on them, so they feel it would be fine to lob a nice gooey bit of saliva to keep it from running. Fucking gross. Roll it proper.
I know what you mean about the grinder. If you grind very dense weed too fine the tip of the blunt "disappears" or disintegrates or something. I call those Houdini Blunts.
I like to break my weed up by hand and pack whole calyxes in my special occasion blunts. No stem, no leaf, just flowers!
Fuck... I want a blunt so bad now. Still another 3 weeks until I'm harvested, dried and cured enough to roll up. Gotta conserve until then.
