Again, thanks for that.
Just to verify, using it on an irregular basis (if it remained that way) shouldn't cause problems? Even when it's only only occasions is it possible that this can cause depression, anxiety, noticeable memory loss, permanent lung damage etc.?
Because, I'm fairly sure I can stay away from being addicted to it. If I say no more than 2 times a week (and on average 1-2 twice a month) then if that's not going to cause problems then things might be good. Then I know if I use it, or feel the urge to use it more than 2 times a week that I am becoming addicted.
Many people on this forum (like the two of you who have posted, thanks for the quick response

) will say that it's wrong and to steer away from it completely. Unless I'm going to build up an addiction straight away like tobacco, crack, p, etc. then I will be giving it a try - so basically what I'm saying, is I am taking on board what your saying even though I'm giving it a try for a while still.
Oh, also - one question about the effects of weed .. can it affect me a few days after I've smoked it? One of my mates who smokes regularly, said that he's felt like he was stoned even when he hadn't been smoking, up to a week afterwards. Since it stays in your system for a long time is this true? My last smoke a few weeks ago, was on a Thursday, I had work on Friday afternoon and felt similar to when I was high on Thursday. Is it likely that was in my head? And being high at work can often be a problem, but if it's almost just the 'after effects', is that a hazard? (That's if it can affect you after a while).
