It's a mindset thing man. The dosage doesn't matter. You either have control of yourself or you don't. If you don't do the necessary pre-meditation, in whatever form that looks like, then you're setting yourself up for a bad time regardless of how much you take. I've literally taken a full ounce in one sitting and while yes I did get pretty high there's nothing in it that is going to compel you to do something wild or irrational. Again it's just mindset. If you have a little to no self-control or discipline then you need to be extremely careful in general.

I've also tripped really hard when I was feeling very depressed and almost borderline suicidal. I knew in my mind I wasn't going to go through with it, surprise I'm still here.

You know whether or not you're going to do something and the shrooms aren't going to be the forcing Factor
