High off one joint? (first time, sorry)

No, I'm pretty sure it's real weed...I got it from a very nice guy I've known for a long time, he's always very honest and assured me it was good (and he's smoked for almost half his life). It wasn't a random hook-up or anything. I just haven't gotten the opportunity to smoke with him yet, he told me to keep trying because it would just take a few times.

 

One thing that's helped me is, inhale a little bit of the smoke before you take in the oxygen. This gets it all the way to the bottom of your lungs (I would assume, I actually have no idea). I used to puff, like I would on a cigar, and then take a deep breath. It seems to work better if you inhale a little smoke, then inhale air.
