How many hours do you stay high from an edible?

Could you please elaborate on the effects and duration of being "high" from an edible? Specifically, how many hours does the typical individual stay under the influence of an edible, and are there any factors that might influence this duration, such as the individual's tolerance, the strength of the edible, or the method of consumption? Is there a recommended amount or dosage to avoid overindulging and potentially experiencing negative side effects?
