Why would you think the mushrooms growing in your pot soil are psychoactive.. Just because they are growing near your plants?
There are hundreds of thousands of different mushrooms.
Most of them are inedible, too woody, too small, unappetizing, a few are delicious, a few will make you sick and a few will kill you, quickly, but not as quickly as you would like.
No one should experiment with their liver, and that is exactly what you are doing.
If you decide to do this really stupid thing on the very off chance you will get high, at least leave a full sample on your kitchen table with a note.
That way the hospital might have a chance of identifying what it is that is killing you.
And then people will, sadly, laugh at the fool who, rather than rely on ten thousand years of human knowledge of mushrooms, opted to start from scratch.
