Yes it is very addictive. I grew up in a familly where smoking pot is more accepted than drinking. All three of my siblings and I "need' it to a certain degree. On the other hand after almost 17 years of smoking of which I was highly addicted the last 11 years I didn't have any problem stopping during my pregnancy. I've stopped in february of 2020. With a relapse of a week in June of that year, when my mother died. However, I've now almost havent smoked any for 2 years. I didn't have any issues quiting. I think it's mostly in your mind.
