OMG! I smoked marijuana for the first time in 15 years. I had a terrible experience from it, I will never touch that stuff again! I felt very very panicky, I felt like a trillion little bugs crawling all over my body, and the slightest move, blink of an eye it would get these bugs moving, but if I stayed completely still this bugs would too. I also felt dizziness, the whole room spinning, and very nauseous. Here it is 3 days later, and the dizziness and nausea have not gone away. What can I do? I have also had headaches since that day.
