Hi 4 days ago (on sunday night) i smoked marijuana, and this was my tenth time smoking and it was definitely my last. I smoked only a pinch of it. Not that much but i still got very very high it was Sativa. And it was also my first time smoking sativa. The next day i felt completely fine until the day after i felt dizzy and as if i was high again but a slight high. Over the past days its gotten worse it resulted in me getting panic attacks because of the feeling. I cant concentrate in school because of how worried and dizzy i am, i feel as if im in a dream, i feel tired & everything is kind of in slow motion. I feel as if i am still high. I am very afraid and want this to go away already. Will it ever go away?? How can i get this to leave my system and feel good again?
