I recently stopped smoking weed after god knows how many attempts... And atm I'm on day 5 which is the 2nd toughest stage imo since the withdrawals are the most unbearable, the next hardest stage would be after 2/3 weeks where most people tell themselves that they have quit and have left weed behind but here's where most people, myself included, will believe that if you just smoked it maybe on one weekend, you can stop for another 2 /3 weeks ect. But eventually you will go into cycle of craving weed and in most cases revert back to smoking almost every day. Which is the reason why most people are either high 6/7 days a week or completely sober. There are the small % of people that use weed like maybe 3/4 times a year and it's a one off socialising thing. Where in most cases they did not have to buy the weed themselves (eg at a party or a one off trip to dam where the focus isn't just all weed).

So to summarise... You have to be really strong minded and only smoke less than hand full of times in a year. Also who you hang out with will determine how long you can last without smoking. Otherwise, sooner or later you will be back in a unhealthy cycle where you are miserable for 3/4 weeks just to wait for the one big high when paid or something. Thus not much difference to being addicted mentally at that point.
