Is marijuana even mentally addictive ?

well im 3 days sober ( cannabis ) and not craving it AT ALL... ive smoked DAILY for about 3 years. Im 17, does this mean im a stronger person ( mentally ) or that cannabis isnt even mentally addictive let alone physically.... id take a cigarette before a joint right now... I quit because im filling out job aps and need to be clean, but i can guarantee i will smoke again, not because i need to but because i want to..
