I m 18 and I ve smoked weed pretty much every day for two years, I have maintained good grades while doing this, I m currently captain of the golf team, and I am working part time. My life is going fine but ever since I ve started smoking marijuana I ve worried about things a lot more, and I have developed a different outlook on life, I have experimented with other drugs such as lsd,cocaine, prescription pills, and Molly but I have never habitually used them like I do with marijuana, this brings me to my question, can anything happen to my brain that is permanent from what I have done, thank you
