Dude I know exactly what your talking about because im feeling like that right now....

Saturday night was maybe my 5th time smoking weed (I dont really count the first three times because I diddnt get high)

Around 10:00 pm me and my friend cashed a bowl in a random persons backyard. We get back in the car and I was like "fuck im sober" then it hit me like a brick wall about 10 mins later. We smoked another one in the G.I joe parking lot and we were pretty ripped at that point. I remember chillin in the car with my ipod and seeing my friends thow a rope over the Nirvana St. sign and trying to pull it down when like 15 grandpas come running out of the dark screaming, foaming at the mouth. It was some funny shit. Then I found myself at my friends house infront of a big ass bong. My first bong experience and holy shit...... Im getting the goosebumps just thinking about it.
It kicked my ass, I think i kinda overdid it but It was the coolest thing ever.

its been three days and everything feels kinda dream like, I was worried yesterday when i started trippin in science class. At lacrosse practice I feel totally sober but when im just sitting down trying to concentrate i feel like I just took a huge ass dip.

As your experience with pot grows, these after effects dont continue do they?

I remember I used to ask what all this fuss about pot was, It took about 5 experiences with it to realize it gets better as you progress... god damn.
