One pointer about weed. To wage a war against weed only perpetuates one's relationship to it, so in the end as with everything it is to see that it is not that weed is the problem per se, but the relationship we create with it and in your case for such a long time all the dependency, the money spent on it, the escapism, and eventually the psychological addiction one creates toward it.
What I see is most relevant is that you are able to ask yourself questions in that moment and then see if you 'really' want to give into smoking again, and so ask yourself if that's what you really want to do? These are 'grounding' questions, though the most directive way that I saw in myself is best to do is when one does not leave even an inch of 'doubt' or possibility to go back to it, at all. I've done the same with weed and alcohol too, it is simply a no go based on the commitment made to myself about it and the realizations I had about why I would 'do it' anyways... it simply makes 'no sense' based on the life I've decided to live and how to support myself. So this is something I would suggest looking at, how to create such resolve so that upon understanding the reasons why you've decided to stop, you make sure you realize that any 'weakness' toward this and having the 'possibility' of giving into it is indicating that there is Still a 'middle way' within you about it, and so that's what makes space for such 'temptation' to exist, because once one decides to not - excuse the frankness - fuck around with ideas on 'doing it,' then it becomes much, much simpler to walk through any possible scenario of 'going back at it.' It takes guts, takes courage, takes strength, but it's absolutely worthwhile investing on these points where you establish your resolve to do something or to not do something and so, self-trust is built this way: you can trust you in your decisions to not 'fall' for something.
About the 'freaky' experiences, I have no direct reference of that, I know of people that have had similar sounds in their mind - women crying and so forth - and all I can say is that it is a result of being too much into one's mind and for that, all I can suggest is to immediately focus back on reality, what is physical, what you were doing in the moment, breath and deliberately push yourself to touch, to see you are physically here and the voices are not 'out there' but within you in your mind and as such: they are Self created - nothing more and nothing else.
I have no direct explanation or idea of 'how' these are triggered, but I suggest you do disclose further WHEN exactly did these thoughts start coming up and these voices, at what moment of the day, what were you doing? or what were you reading/watching? Identifying the context in which this emerged within you will enable you to start 'tracking' the pattern, at least to have a self-reference of WHEN they come up and possibly why they come up. Sometimes it might be stuff that is ingrained within you as thoughts you had participated on in the past and suddenly come out as a 'broken record' as it is stuff we allowed ourselves to be 'thinking about' for a long time in the past. These are ideas I'm placing out here which are assumptions and as such shouldn't be taken on as 'the actual reason for it all.'
So, I suggest listening to the series of interviews of The Future of Consciousness as well, as there are various interviews that explain these points too and generally the solution and problem-solving situation is still the use and application of the tools you already know and are aware of. It is important to not give further attention to it all to the point of actually becoming scared of them, but instead self.-forgive in the moment, breathe, ground yourself in the physical as in realizing it's all in the head, no need to participate and so, do not create any fear around it either: it cannot be something 'there' inside your head or actual people or things 'outside of yourself' = it is all within you, and that's the certainty you can have as well, that no one or no-thing is doing this to you: it is all self created.
This is what I can suggest doing for now but do share if it comes up again.
Thanks for sharing and I agree with Mike, you can count the blogs you've done thus far and start placing a number upon the next one.
