I want to make some sort of funny joke about "where do I sign up" and all of that, but I've got a confession to make: I'm not very good at rolling joints. I'm actually horrible at it. I do have a roller machine that I can utilize to make it easier. It's small and easy enough that I've always sort of depended on it as a crutch.
Smoking joints uses more weed... I don't know that it's fair to say it wastes weed, though. If you've got enough, and you want to smoke a joint, smoke a fucking joint. It's okay. It's a plant. Just like if you like more basil in your pasta sauce, just put more basil in there. Don't worry about running out of basil and then eating shittier sauce.
