Not to long ago I tried weed and it was all to weird to be honest. It was relaxing but a bit to relaxing for my liking. While I was while I was scared every time my heart rate increased (which happened regularly) and thought I would die. I knew I was high when I looked in the mirror and I saw someone smiling at me. It scared the living sh**s outta me so I feel asleep. However since the 4 eel have passed, I occasionally feel the high like symptoms, and it makes me really scared, especially due to the fact I smoked it once 4 weeks ago. Should i be worried?
