The amount of time it takes for an edible to kick in greatly depends on your metabolism. Some people with faster metabolisms may start to feel the effects after about an hour, while those with slower metabolisms may not feel anything for two hours or more. The effects generally peak up to four hours after eating or drinking cannabis, so it's best to wait at least that long before consuming more. In most places, 10mg is considered to be a dose – which may be just right for some, but others might need a lot more to feel the same effects. Take your time and learn what's right for you, and always pay attention to the label for dosing and recommended serving size.
