That said, I feel like I drifted between the two categories you describe. Sometimes I'd chill on the couch and do nothing but consume. Others I'd feel inspired to do something productive, like work on a side project, clean the house, go for a walk, or practice guitar.
Weed makes consumption more enjoyable, therefore you consume more than you'd consume without weed, at the opportunity cost of doing other things. Which in general makes you more boring.
I've been around stoner friends a lot (for most of them it was a phase in life which they got out of before ~30) - no matter how boring / interesting they were before / after weed, during their weed days they were more boring than during their non-weed years. Weed makes you content just sitting at home while otherwise you'd rather seek some excitement outside.
People might have other experiences than you lol! Maybe someone finds watching sitcoms stoned while knitting to be the most rewarding thing in the world? Maybe they think the things you're doing are boring? It's odd to judge what people find exciting in life.
One set smoke weed and then partake in creative, explorative, or otherwise effort filled pursuits. Generally I feel that weed has likely improved their lives.
The other set smoke weed and consume... consume tv, consume video games, consume food, consume music. These people seem to fall into a slump that weed seems to participate in keeping them in. Weed lowers the bar to enjoy yourself and thus raises the bar for other activities. If weed and video games feels good, then why call up friends and go bowling? It's not addictive, but it does have a kind of gravity because it's an activity that participates in the economy of potential activities. For these people weed entertains them, at the cost of them becoming a more boring person.
