How this index is built
Each priced flower listing in Petaluma whose package size is published on the menu is converted to a price per gram. Listings with no published size are excluded rather than estimated, which is why the listing count here is smaller than the total menu count.
Go deeper: cheapest weed in Petaluma, cheap ounces, cheapest flower per gram, Petaluma deals.
Figures come from licensed California dispensary menus and change constantly. Adults 21+ only.
