I took 2 weeks off weed and then bong bowled about 0.1g-0.15g of some sativa I had just grown, it was the first stuff I grew.
It was also my first T-break. I built my tolerance on shitty mids (which was fantastic for my depression at the time, it woudl have been a shame to trip face on weed unsuspectingly, but it chilled me out).
With a tolerance, my highs are generally euphoric/chill/minor closed eye visuals and open eye visuals (If i look I can see grids on the sealing, other places).
Without a tolerance it was a nearly entire psychadelic head high (This was a heavy sativa that I harvested at almost completely milky trichomes, so kinda early). Off that small bowl i started off by mildy tripping face, feeling my mind split and two and the two halves confusingly arguing with each other, I then laid down on my bed where I was completely paralyzed for about 3 hours; the entire time my body buzzing far harder than was comfortable. My cell phone was about an inch from my hand, for three hours I coudlnt touch it.
I closed my eyes with heavy patterns and grids, and literally whatever I wanted to imagine showed up in the center of my field of vision. I imagined weird ass shit just to test it, as a reaaaaaaal test I imagined one of my lady friends nude (perfectly)(Fuck off it was just a test lol). Anyways, shortly after that I had a CRYSTAL CLEAR closed eye vision of a my mom's car driving down a highway (i could say the exact place/direction/which cars were around it), and then the car got into a massive crash and pileup. It could have been 1 of 4 people driving I did not see that.
After this and the few days following my tolerance kicked in and my highs were much more comfortable and mellow.
I guess it may help to add that I have had somewhere around 30 psychadelic experiences, and this one was probably around 6th strongest. It was not fun. I do not suggest trying to trip face on weed.
As far as OP goes, even with a tolerance I generally get slight open eye and close eye visuals (mostly patterns and grids). Sometimes if I get stoned enough I can get open eye color distortion. Not long ago I was looking at a camouflage blanket and it looked like it was a red and blue flowing river, the other colors in the area were distorted as well. Then i conversed with the trees (It was a very inspiring 1 way conversation, but I could tell they were listening...hah.). I'm unsure of how I got that high on cannabis comfortably, but it was only comfortable.
