Is 2000mg in a edible too much?

Basically I’m having a back and forth on the safety of this as I’m being told this will induce psychosis. I personally think it’ll be a great time. Essentially I have 120 grams of dust including some stems but not a lot. This dust compromises of stardawg and other strains that were grown in Thailand. I’ve assumed a 20% avg thc content so 24,000 mg of thc. I wanted to make 8 separate edibles but I’m being told this will damage your brain. I did this before with somewhere between 40-60gs granted that had alot more stems and the high was powerful but I enjoyed it. Could someone give their two cents and also if you have better approximates for what I should expect the total thc mg to be from 120 grams id appreciate it.
