I mean weed really doesn't smell good. If you're not turned off by the smell, it's a learned pleasure. Similar to how nearly every child will dislike the taste of alcohol, yet after drinking for a while they'll learn to tolerate or enjoy it.
It can be a very overpowering smell. When an odor overpowers, it's harder to discern one scent from another.
A few years ago, I moved from San Francisco to a rural area. Smelling weed in SF was not at all unusual. One summer night in the rural area, I smelled it coming through open windows for the first time. I wondered which house it was coming from and how it still smelled so strong after traveling a hundred feet or more. Then I spotted the actual skunk in our yard.
