Do you use marijuana every day or almost every day? Have you tried to quit but can’t? Do you get unwanted symptoms when you stop, like anxiety, crankiness, or trouble sleeping? Do those go away when you use marijuana again? Do you have a strong urge, or craving, to use it? Do you keep using it even though bad things happen, like problems at work, school, or with friends and family? If you answered yes to any of these, you may have CUD.
