Does anyone know someone that smokes weed daily and live a productive life?

My boyfriend is 34 and smokes weed everyday. I didnt know he did it all the time everyday and i dont think i can dal with it. It makes his breath smell bad and his clothes. He is 33 and i think he is too old to be smoking like a reckless little boy. he does have a job as a dental sales rep but still dont know if this is something I can deal with. I know its not all that bad but i barely want to kiss him because it makes his breath smell horrible. Is this the norm, does anyone else know someone lke this that smokes weed? Should I stay with his guy, I am on my way to being an RN and i like him and all but this is questionalble behavior. Not to mention he can call me excessively sometimes, like 20x a day, when he dosnt hear from me in a few hours
