well if you don't see it negatively it's going to be impossible to quit, might as well move to a state where it is legal and honestly any drug is bad only if it is abused, if you feel that marijuana does not impair your ability to live life to it's fullest but rather enhances it and if you are 100% certain that you are not using marijuana as a form of escapism then I see no reason for you stop.

Best of luck
