i started smoking pot when i was 16. I have been an everyday user since I was 17. Because of my intelligence and entrepeneurship, I was able to smoke half an ounce a day for my first and second year at university. I am now in my fifth and final year and I still smoke around 1/8 of an ounce a day. I am currently in a class where we learned about Grave's disease and I was certain I have symptoms of it and that it is caused by smoking pot. It was because I was doing more research on it that I found your post. If you are interested in more of what I have to say, feel free to reply to me.
