You're still alive. You are fine.
& if you're interested in hearing a (what I will attempt to make small as f@#k!) story about when I ingested a synthetic compound an old friend had given me, and it's repercussions read on haha.
I once ingested a substance that set the sail's in which direction my life would be going for a while.
Unfortunately, lots of chemicals nowadays that are marketed to users are not what they seem. I can't tell you how many times I have seen kids ingest DO-x compounds (DOB, DOC, etcetc) marketed as LSD (including my girlfriend who had an extremely profound experience...). In my opinion these chemicals are not and were never meant to be ingested by anyone or anything, but most people are "about their money" and don't really care what happens or how a user feels after the substances are in your hands.
I'm sorry about your experience and I'm glad you're doing better, the anxiety and paranoia will subside with time- just relax and take it as it comes and realize that you aren't "damaged goods" and that you're going to be completely fine soon.
An old friend of mine that I once trusted more than anything, comes up to me one night.
He tells me "XXXX, ROLL WITH ME!" we used to hustle a lot of MDMA back in the day and so naturally I trusted him.
Everything in my gut this night was telling me not to do it, but I did anyway. So I eat this capsule of "MDMA" and it hits me, I can tell it's not MDMA- but an analog, it was whatever.. previously I had eaten analogs and RCs before on rare occasions and been fine with them, but they weren't exactly my favorite so I was slightly miff'd... haha
The night is moving on and I'm feeling out of my body- in complete and total bliss; hugging someone was the greatest feeling I had ever had. Having a conversation with anyone was the best feeling I ever had, walking, talking, drinking, EVERYTHING felt amazing, I felt on top of the world, and in the clouds

So I walk to the kitchen to grab some water. Put the water in my mouth, and notice that I immediately felt nauseous, I swallowed the water and my stomach was very upset. I'm walking back to where everyone was sitting outside holding my stomach, I sit down once I am outside and attempt to sip the water again, same effect.. except this time:
ME: "I think I'm gonna be sick, I don't feel so good"
XXXX: Are you o-
VOMITING. EVERYWHERE. PROJECTILE VOMITING. disgusting, something was wrong. I started freaking out, perhaps having my first panic attack/fit of anxiety? For some reason I couldn't hold water in my stomach, and water in my mouth made me extremely nauseous ?!
So I walk inside the house, my friends are following me. The owner of the house notices my chest (wearing a shirt with a few button ups on it) I was COVERED in red blotches = allergic reaction.
So.. rush to wal-greens didn't really know what to do, was completely honest with the pharmacist he opened up a packet of benedryl for me I took the benedryl and eventually the blotches went away-needless to say my night is turning out exactly as if I knew how it was going to turn out previously to ingesting the chemical...
The whole night was filled with strange occurances and feelings- terrifying ones. I felt awful, nobody gave a shit and everyone was like "Oh you're just fucked up, you're just panicking, you're going to be okay" despite begging for someone to bring me to the hospital.
This is going on really long, and I'm going to skip most of the occurances unless someone ends up being interested in this story at all and asks, but one very profound thing happened on this night.
I was sitting on a couch in the living room of the house late, late, late at night with nobody awake- just me, in all my agony and panic accepting death soon to come (lots of signs of brain damage, etcetc lots of strange things happening, so of course I assumed the worst)
I am staring at the wall for some reason huddled up in the corner of the couch. All of a sudden, I see a green translucent door appear in a foggy green mist on this empty white wall. I am sitting here.. saying nothing... knowing nothing of what is happening, also keep in mind the RC I ingested was NOT a hallucinogen of any sorts but what I am thinking was more of a synthetic amphetamine.
A woman, appearing in the same fashion shows up. She is green and translucent, and facing the door. Her hair and dress were waving in "the wind" and I could not see her face. My eyes open up VERY wide and I sit there in silence thinking to myself "is this it? what the hell is happening?"
The door opens wide up. Inside the door: nothing but black, emptiness.. against this blank, white, wall. The woman sits there for a moment, doing nothing... and walks through the wall into the door. The door closes, and dissipates.
And that was it. After that, the next morning I am still just as fucked up, pupils JUST as big as they were when I came up and eventually someone brought me to the hospital.
Toxicity report: Extremely unsafe level of amphetamines in my body. Gave me 8 MG of Ativan (fucked me up again, hahah but felt MUCH better..)
/End
Needless to say.. the following MONTHS and MONTHS were awful (this happened LAST year around this time). I was plagued with HORRIBLE anxiety.. I couldn't smoke cannabis anymore because it caused GREAT anxiety in me, and I became a completely different person and I hated it. Nobody would help me, I was forced to purchase benzo's off the street NOT to get fucked up (i am totally against pills) but just to relax, just to feel normalcy once again- just to be able to function during the days.
I would often times have terrible sleep paralysis and "brain zaps" where I felt like I was dying/seizing/"exploding"/stopping breathing/my heart was stopping in my sleep. I would be stuck up all night smoking cigarettes and drinking coffee to stay awake, and only recently has my life begun to get back on track.
So basically all I'm trying to say is you are very lucky to be in the situation that you're in, rather.
You're gonna be okay, and if you ever need any type of help Dmt-Nexus look's like they have people who care!
AND to answer your last question, Marijuana IS classified as a psychedelic therefore yes some people's pupils will enlarge when smoking cannabis with a higher percentage of sativa.
...I also suggest NOT doing drugs like meth... you only need a wee bit of commen sense to understand what drugs are safe and what drugs are NOT safe.. take care of yourself.
