Good topic! It effects different people in different ways. I think this also has a lot to do with how it is treated and produced.
Marajuana produced for legal purposes is much better than any crap you buy off the street. Also in Amsterdam it is a completely different experience.
I CANT smoke it anymore because i get the fear and once you get it, its incredibly difficult to overcome. I figured that why do something that makes me feel so bad and scared.
I do have to point out though that it is linked to paranoia in some people and if you have underlying depression it really is not a good idea to use it.
Also when you are stoned all the time, you do not actually listen to anything really. You tend to do the same thing every night, watching the same film, having the same conversation and it is extremely boring if you are not stoned.
Is a personal thing really, some people can use it recreationally, some use it everyday, for some it is a start in a life long love affair with drugs which may end up in premature death. The thing is unless you try it you will not know how it will effect you.
I would not recommend that everyone go out and try it though that is NOT what i am saying.
I beleive that it is illegal because of the long term effects it may have on health services and mental health problems. There are a hell of a lot of depressed people out there and marajuana makes it a hell of a lot worse.
In Amsterdam they issue a warning that if you are suffering from depression you should not use marajuana.
It seems crazy that you can make a plant illegal, yet i believe it should be simply because on a world wide scale legalisation will increase mental illness.
Thats my 2c anyway
