Weed made me a much more social person. In high school I'd rarely hangout with people (maybe once every month or two) but since smoking I'd hang out with people like every day. Smoking with friends is much better than smoking alone. Also it gave me a huge appreciation for nature. I now see the beauty of plants and forests and such.
I used to have high anxiety and depression. The anxiety is gone and the depression has gotten better. I'm much more relaxed and don't let little things get to me. I have made some excellent friends that I would not have otherwise. But the biggest thing is, when I was 16 the eye doctor found the begining signs of glaumcoma. At 25, I currently have no sign of it anymore! I love this stuff!
