I never had a problem smoking outside anywhere, just don't smoke in your hotel room. LV law says only in private residence but I was burning joints outside Aria, Resorts World, Wynn, etc valets in cigarette smoking area. Just be respectful to folks who don't like the smell (if they ask or you get the impression) & you'll be fine.

From my experience most dispensaries are the same, just avoid places like Planet 13 (prices hikes up for tourists, though I never went there). I went to a place called The Grove (cuz it was close to airport) once then a place called Green a few times which was very nice & had good prices/deals. I didn't have a car otherwise I would of tried NuLeaf and other recommendations. Daily/weekly deals seem to be the thing to follow in the scene.

Hope this helps, have a good trip!
