I've heard cannabis described as a multiplier and I've found that to be true. For me it makes allows me to notice what I'm feeling more (physically and emotionally), food tastes better, I write more, my mood seems elevated, but it has it's downsides. Around people and in public my anxiety is much higher and like others, my executive functioning and memory gets worse.
I also find my thoughts feel more "linear," in a way: slower and easier to trace how one thought led to the next (if I'm able to hang onto that thread). It's easier to observe my thoughts. If I have one thing to sit down and focus on, it's fantastic. If I'm interacting with a lot of people and having to task switch a lot, it's a nightmare. Again, that multiplier effect, as I'm quite introverted.
I also don't get tired from cannabis. I can't do sativa. Too much anxiety. I go for heavy indicas and even that can light up my brain. If I'm in a space (physical and mental) where I can relax, it can occasionally help. I go for edibles, usually 1:1 THC:CBD; 5mg of THC. I use about once a week in the evening when I have a project I'd like to spend time with and I won't be bothered.
I was doing that 3 days a week at times. I took a 4 month break while I started my medication for ADHD. Started back up recently. Honestly, I think the cannabis might have a better overall impact. Correcting more data, but I might need to change my meds.
