I don't know if you realized it but you posted an interesting topic. I am an old user on this forum, very educated, very smart and very lucky when it comes to my lifestyle. Do you know that I can take 100mg, 200mg...500mg, of pure d-amphetamine, and I still remain sober despite hearing voices, seeing Santa break into my home? It's good that you can stay sober on weed, but know that other people like myself can freeze themselves to shit with hard drugs and still be as sober as Judge Judy.
I can give you an example you can understand, masturbating to a pornographic movie until I perceive the woman in the video being with me for real, part of a dream or fairy tale. Despite all of it, I know how much I took, when, and I know that, unless I ejaculate within 2 hours, the fairy tale will go away and I will be sitting there wondering why I'm watching that non-sense. Not only I am aware of changes in perception and I can also tell reality from the psychotic side effects but I can also plunge in the psychotic side effects and use them for my benefit, while also remaining perfectly rational and making good decisions in real time, while being in a state that would give anyone else a panic attack and leave them traumatized for months.
Another example would be, in the depths of psychosis, at 3am, I can set the alarm watch one hour earlier, at 5:30am, because I'm able to tell that would be enough for a deep sleep stage, before I wake up to take more amphetamines and go back to sleep, so i can look sober one hour later, at 7am so I can go to work. I'm talking about advanced level planning that I'm able to do in a state that most people refer to as the reality of a fly or a bug, something 100% irrational, because they haven't found a way to keep some minimal cortex areas lit up during that time.
It is very good that you actively try to remain sober while you're stoned, it's good practice. The rest of the idiots will tell you if you wana be sober, don't smoke. Let them be idiots, their life is worth what it is worth at the end of the day.
