Last week, we asked GP readers a simple question: what are the most useful cannabis accessories? Through a thicket of submissions from Bob Marley and Willie Nelson, some seriously insightful picks shown through. From the first smart bong to the difference between 91 percent and 70 percent isopropyl, these are GP readers’ favorite pot accessories.

“Does everything, folds into any shape. Clean bowls, tighten up joints. Makeshift grinder, just pinch against buds. Costs nothing. The perfect tool.” —AB
91 Percent Isopropyl alcohol

“I don’t smoke a lot but when I do I like to use a bubbler. Bubblers need to be clean and are at the same time notoriously difficult to clean (due to their small size and fixed stem). 91 percent iso (not the 70 percent stuff you use for disinfectant) is the key; after every couple of sessions, I take an ounce or two of iso and swish it around vigorously in my pipe just rinse with hot water and let it air dry. Works like a champ and costs practically nothing.” —Rob
