Yeah dude, don't give up just because you never got to smoke that first sack. When I first found out how great weed was , I immediately thought "Where has this been all my life?" If you pass this opportunity up, trust me you'll be missing out on a lot. If you don't feel anything on your first try, still don't give up. I didn't get high my first time (just coughed a lot), but I must have the second or third time or I wouldn't have continued (I don't remember my first high, which I take as a sign that it was good). Also, the potency of the weed has a big effect on what you feel. If it just looks like a bunch of chopped up leaves, it's shwag and you probably won't get very high off a gram, but if it comes in a few buds you should get high. Look for the tiny white crystals on the buds -- if you see a lot of them, that's a good sign that the weed is potent.
