the high, you get from pot is almost impossible to explain, and the effects are dramatically differnet from person to person, so describing what will happen to you in itself isnt possible, however there are many common side-effects from weed. These include, hunger, euphoria, and a differnet mindset, or a changed way of thinking about things. Through my years of smoking i find the best way to describe it would be that it simply enhances all your senses, and just makes everything better. Lights usually look brighter and deeper, feeling is enhanced, smells are stronger, taste of course is greatly changed. The only thing i can advise is that if you manage to get really high, you may have these great epiphinies (spelling is terrible i know) , however usually these great thoughts arent really that great and to one who isnt as high as you, they may seem stupid and annoying. Try to talk but not alot, and dont share every thought that crosses your mind.

Good luck
