Also when you say coffee smells good and cannabis doesn't - highly subjective right? I love coffee, but some really high quality coffee smells like s*t haha (literally). There are some fruity, piney, lemony, and floral scents from fresh cannabis, just like there is a nice aroma from fresh coffee. In both cases you're talking about a flowering plant, with highly subjective smells and varying terpenoid profiles. However, note that the terepenes "pinene" "limonene" etc. in cannabis are the exact same plant terpenoids in pine trees, lemons, etc. so if you like the smell of pine trees, lemon, mangoes, roses, and other highly floral scents, you will likely also at least appreciate the smell of cannabis.
I've said too much for Hacker News!
There's nothing subjective about not wanting smoke in my lungs. If someone wants to get pot buzzed, go eat an edible and waste a day of productivity for all I care. Smoking the entire house, and costing me my deposit while justifying it with "George Carlin wrote jokes on weed" is peak pothead narcissism that makes me want to have it permanently banned.
There's also a big difference on a social level. Have you ever had a pothead as a roommate? The entire house smells like a garbage dump 24/7. Whereas freshly ground coffee actually smells good. Coffee addicts only bothered me with their unwashed V60s lying around in the sink.
