I smoke a shitload of weed, and I go to yale. I am a senior studying international affairs and political science. I was just accepted to Yale Law School. It's what you make of it. Keep weed in its place, and never allow it to get a stranglehold over your life. Be a man, know your limits, plan everything, be confident and, most importantly, don't be pussy out. University is a lot of hard work, and Law school is going to be a bitch. There are times when I have to go without smoking pot for months at a time. I usually have to wait until spring break or weekends. If i'm taking really hard classes, I have to put in 50+ hours studying a week. Pot will distroy your grades if you use it all the time. Sre, I've been high as fuck in easy courses, but when it comes time to put up or get out, you have to make sacrifices.
Just think. You'll suffer a little, but when you're making six figures, you can smoke all the weed you want.
