Myself if I stay away from any cannabis projects for about two weeks I can almost forget that the stuff exists. However, if I have the stuff around I find it almost impossible to say no and I rapidly dose escalate. My guess is that cannabis smoking has both an irritating and anti-inflammatory effect so if I am smoking my breathing is OK and if I am away for two weeks I am OK but my breathing gets bad maybe 4-5 days after quitting. A vape just doesn’t do it for me.
