I partied with college kids (among others, of course) back when I was that age. It always seemed to me that, if they were drinking wine that day instead of something flammable, it was because they were all down to collectively pooling their change - or that rich @sshole's daddy had finally cut him off from sucking at the family tit and told him to go get a job and work for his money like all the other normal folks - and had found a great big box of the stuff on sale.
Things must have changed, lol.
Some folks don't smoke it. You may have noticed by now that Sue uses cannabis via multiple forms of... delivery? Don't confuse decarboxylation with the method of delivery just because one method (smoking, IOW, vaporizing it with a high degree of combustion (vaporizing also decarboxylzes, BtW)) happens to do that thing. Many people would continue to smoke and/or vaporize their cannabis, regardless of whether decarboxylation was still necessary at that point or not. Different delivery methods have different effect profiles, strengths of effects, effect onset time, and duration of same.
And, at the end of the day... It turns out that a lot of people do the things they do because it's what they're used to doing. Or because they like to. I've been known to roll one up, myself, just because I felt like it. My brother rolled so many joints in the '80s that he got to where he could do it with his eyes closed, while walking down the street, while sitting at a stoplight, in an amazingly short period of time, et cetera. He hardly ever does these days. But once in a while, he just takes a notion. His joints look machine-rolled, lol. He never really got into the fancy stuff, just take a paper, put in some cannabis, roll, and stick. Although I can (vaguely
) remember one New Year's Eve party when he just rolled an empty paper end to end, stood the cylinder up on a table, grabbed a lid of bud, ground it, and proceeded to put it into the paper. IDK how many people that thing would have gotten there - because we ran out of people. You'd think it wouldn't last all that much longer than a regular joint, just hit harsher. But that thing seemed to make its way all through the house and backyard, too, lol. Although it was a little harsh. (About blew your head off, actually. Don't try this at home, folks - unless you've got an extra ounce or so laying around.) Might have had something to do with the fact that he kept adding a little bit, then tamping it down (with a pencil? I don't remember), then adding some more, then tamping it down, then... THAT joint took him a few minutes to create.
Reminded me of the cross joint Canna rolled last year. That woman is amazing. She rolls a joint much like you describe your brothers prowess. In Jamaica it was Canna we turned to when it was time for a community joint-fest. 
I'm figuring another two weeks and she'll be in the tent. 
I'm ready to get breakfast going and start this new glorious day. We've had wonderfully mild days of late, and today feels like another of the same. Hopefully I'll get out to the river today, although the I want to get Callanetics in first, I think. I keep putting them off until later, and later turns out to be 2AM.
