The thing with cannabis (with THC) is that it makes doing nothing OK so you may realize after some time of daily use that you have accepted doing nothing as a legit activity, contrarily when not high you'd either do something to utilize that time or may feel bad that you have nothing to do (bored). Cannabis has not much of physical addiction properties which is great yet one day you may find 10 years have got behind you and you have done not much. Perhaps no one told you to stop consuming it daily or you have just drifted upon losing the handles on your life.
If you want to be a daily user, or already are, do try to still feel the need to do something when there's nothing to do and consume it responsibly. You probably will be fine health-wise but remember that doing-nothing-is-ok is not ok especially when it's become routine.
