My Mother has tried hash tea as new medicine option to see if its really help her to calm down and I have tried one cup too.
It was nice. While everything is almost tasteless for me, I was so surprised to fully taste the vanille ice. Indeed I was feeling more calmer and lighter too.
But beside the good points I had sometimes hot flashes and sweats much.
But I can see how its could help with mental illnesses. My mother feels better this day and would try it again.
You only need the right dose.

And of course it was a strange feeling to try it at all, but I wasn't stoned afterwards, I was normal all day. I even ask my Partner later, he didn't know it and didn't realize it xD
