It's a bit similar but I don't think it's good to make second-hand comparisons. Cravings are not a simple binary. Like, if you consume cocaine for pleasure then you can have a craving to keep doing more until you run out or its time to go home or whatever. But below a certain threshold the craving isn't that strong, so you could have a little bit and then get on with your day, much as you might have a cup of coffee in the morning but you don't necessarily want it round the clock.
