Hey there, thanks.

I would say that the only effect that phenibut has beyond its effects is of the same nature by which anything can have that effect. That is, by feeling a boost of self-confidence or social confidence or whatever, you have now felt that and are able to experience it and gain more confidence simply because of experiencing it. So then, ideally afterwards you would retain some benefit. That's really similar to how psychedelics work too really, it's like, if you get there, you've been there, so you can perhaps make use of that experience to inform your future perceptions. Phenibut has probably provided some of this for me, though I'll also say that when I was much younger alcohol actually helped me to become more socially confident in a permanent way too, so it's not a property unique to phenibut nor is phenibut really special in that regard. I would say psychedelics have provided me far more utility in terms of long-term benefits to my life experience. But like I said in the report, I do think phenibut could be a good candidate for a transparent, non-threatening psychotherapy tool to aid in opening up emotionally. Just like how MDMA is starting to be used for this, but less extreme. Through increased openness and focused effort, I think people could gain long-term benefits as a result of working through issues with the help of phenibut.
Phenibut definitely has a draw for me, but it is not in the same league as opiates. I will say I am reducing now and I am going to take a good break from it, as I am starting to feel some weird body pains and I have the feeling that years of every other day phenibut use without breaks are not good for your health. I think it's best used sparingly. Using it up to every other day for periods of time where it provides benefit seems great, but I have been using it for longer at a time than I should, I have been feeling recently.
So yeah there is some interaction with addictive personality stuff, but not even close to the same sort of level as opiates.
Phenibut reacts with marijuana the same as it does with basically everything... it just provides a base level of anxiolysis and euphoria, which the other drug then rests on top of. So marijuana's positive effects are more emphasized, paranoia and anxiety are a lot less likely, but it doesn't change the nature of the drug.
