I would say no. The effects from the thc are long gone by now.
I would agree with hopsing. I used to smoke pot a lot, like everyday for 2 years, and once I stopped I never felt any effects. Maybe you are sick with something. You should see your doctor. One thing you need to be careful of is people lacing the pot with coke, heroine, etc. Do you think that may have been a possibility? Do you know the people you did it with very well. Hang in there and just try to get some rest. If things do not improve in a couple days, I really suggest you get to a doctor. Hope you feel better. We are here for you if you need to talk!
I agree that the THC is gone, however....What your so called friends did was inexcusable! I am sure that did some damage to your psyche. Do you have access to a counselor? It might help you.
I am sorry this happened to you.
