Alright guys, sorry for such a late post I was really tired during the past 2 days
Anyway this is basically how it went down. We had 6 guys, 4g of weed and 1 water bottle bong.
We went into a trail and jumped across a little water stream into this corner where we could barely see the trail.
Then I saw the weed and smelt it, it smells pretty odd but it was my first time

. We started to smoke the weed using a water bottle bong. I absolutely have no clue how this thing works but we all got stoned. I took about 6 hits(yes I'm weak LOL!). All I can say is that it really hurt going down and I was coughing a lot. While we were doing this, we herd something from the road and we walked a bit deeper into the bushes. Once we got a bit deeper we started to take more hits. While my friends were playing music this black car pulled up right by the road where whoever was in there could see us so I told everyone and jesus did we have fun running and jumping over the stream. When we got onto the trail my friends were fked up!!!! I didn't really feel anything. When it started to get dark I started to feel really sleepy and tired. After we got REALLY hungry and we all made a mistake and we didn't have any food. So we hit the McDonalds in the walmart. While we were walking my friends started to feel the weird, it was like a side I never saw to them before. I felt really tired and I started to get very paranoid and scared about being high. Once we go to the McDonalds my friends ordered a **** load of food and they ate LOL! While I was in the McDonald I felt really sleepy and I felt like I was floating!!!! When we left I started to burn off. In the end I think it was worth it but not something I would do again. Like everyone said, everyone is different and my first time wasn't the best haha
To answer my own questions, this is how I feel atm :
1.No, not addictive at all
2.It made me see some shadows at the corner of my eyes while I was in the forest
3.First time was pretty hard. Got really tired and felt like I was floating

4.Not sure yet
