Obligatory, everybody's bodies are different, what works for you might not work for everyone, ymmv, etc. I have used marijuana medically and will state without question that it is an addictive substance. Whether that is the multiple shitty feelings you get from stopping abruptly or the deep unending desire to 'just smoke a little' in the three days it takes to get over or. I think those 'comparatively little' things are enough to consider the drug an addictive substance. I've watched people drop out of college to smoke away all their money, I've watched kids lose all their friends and think nothing of it, I've seen people incur great risk of physical harm to acquire weed when they were out or sit in their house descending into self hate because everyone else was out too.
You may be able to quit easily but it is wrong to apply your experience to broad statements like, "pot isn't addictive". Marijuana is an addictive substance and I wish this anti-prohibition mindset I see so many places would fight for science, not just weed.
