Tolerance develops after using cannabis for a long period of time, once your body becomes desensitized to the effects. This means that it can take large quantities of bud to get the same high. Toning down your weed intake can be a good idea, especially if you’re a veteran developing a tolerance.
Are you smoking weed but not getting as high as you’re used to? Are you spending more than usual on buds? If so, it may be time to take a tolerance break.
