It's all bullshit. And all in your head.
I smoke alone regularly but when I finish off a nice fat bag, I take a break. 1 week at max. Usually going on 2 or even 4. After the first couple days the urge to smoke subsides and I get on with my life just as if I were smoking regularly. I will turn down free weed if I am on one of my breaks.
People do argue the fact of psychological dependence but that is the person. Not the weed.
I feel I can stop freely anytime I please. And I do.
