Replying to Smokin dope as a teenager

I'm 15, soon to be a sophmore in highschool and i started smoking at the begining of freshman year, I have been caught twice, once on Halloween when it was my friends first time and he freaked out hard and told his parents and me and 3 other kids got caught, and the other time my mom found my stash. At the end of the school year I became friends with a new group of kids and we have a group message about hanging out and smoking and it started off with about 15 kids and now it's down to about 4. All the other kids got caught but they either made up a story or their parents were pretty cool about it and didn't tell my parents. We smoke together like 4-5 times a week in some little place in a forest place down town and just hang out there. But how did you guys do it? I usually just roll a J or 2 and my other friends bring weed and either a bubbler or bowl. How did you guys get your peices? I get packs of papers when I buy weed when I run out. How did you guys get money for it? I usually get a G of good weed for about 10$ but usually buy like 5 gs for $50 at a time. And most of all how did you guys keep it from your parents? I was drug tested a while ago but I drank a ton of water and somehow passed so my mom isn't suspicious any more.
