If you want to know how it effects you, theres only one way to find out. No one else's opinion can properly describe it to you, its something you need to discover on your own. If you really want to find out, i suggest taking part in a few sessions, at least 4 or 5 in number to be sure you get proper results. It affects everyone differently, and some people have higher/lower tolerance than others.
Through my experience though, i see few cons. Im not going broke or into debt by spending all my money or anything of the sort. I am lazy sometimes (everyone is) but my overall strength,physical abilities, and body type have drasticly improved since i started smoking, but it has also been coupled with physical activities much of the time. My mind has also been opened to a whole new plain of ideas and thoughts, and many relevant points involving reality and the world around me.
Just try it, it will not harm you, even though it may seem so when you first start smoking it, because you are not use to it. But in time, you will realise what the hype is about.
Or you could realise it is a waste of time.
