Ok so I use to smoked continuously for over 2years everyday but one day I smoked and I coughed super hard until I puked... But the high felt like any other high until about 15 minutes chilling I instantly feel completely numb my vision is 20/20 really bright I know it was weed but I was freaking out and hallucinating I quit smoking for 6months after that scared me shitless, but about 2months ago I picked it up again and just took a couple puffs everyday to help my neck problems, but once I again I smoked about 6 bowls with my buddy coughed again and puked and started tripping again idk what this is and if its natural idk if I should just quit or what to do not to cause this to happen, I want to know what happened and why I was hallucinating and if anyone has had the same experience, just someone explain why this is happening.
