I'm a non-smoker and non-drug user myself. I remember doing an edible. I was told to do a half portion to start.

I wasn't feeling shyt after like 30 mins, So I ate the other half.
After like hour or so, I was high as fukk, but still kind of enjoying it.
After another hour, I felt like I was gonna die. I was all over the place and panicking and doing and saying all sorts of stupid shyt.
I had eating before and I could feel the food just sitting above my stomach not digesting.
I tried to drink some vinegar cider to help it digest, and then I puked all over my carpet.
What a fukking miserable experience.
