Tyrant

So yeah, been smoking for a year.. sometimes I won't smoke for a couple monthes sometimes a couple days in a row, I don't own my own bowl or buy weed.. i've probebly smoked like 30-40 times total in my life. I have a weird High.. I don't understand it.. basicly when I smoke with my friends i'll get extremly high off 3 hits, I will change my voice and almost act out different voices and act extremly silly. I will laugh at just the slightest look of someones faces and laugh for a good 2 minutes until my chest is hurting from laughter. I basicly have the lowest tolerance of anyone i've ever heard of, smoking with friends today they all are calm and relaxed and as soon as i'm done 2 moderate hits i'm completly done.. they finish off 2 more bowls, I take 1 more hit and i'm still stoned right now, its 9 hours later and my words are still slurred some and my concentration is focued on only one thing at a time. Now I thougt maybe, because I'm adopted and don't know who my real mother and father are.. it could be something to do with my mom or dad smoking while she was pregnet with me? can that happen? I sometimes feel depressed when I smoke towards the end like.. its retarted that i'm doing it, but I generally have a good time and don't over due it. Just trying to understand why my high is like insanely good.. any thoughts would be much appreciated.
