More scientific research showing the bad side of marijuana usage:
However, it may be more complicated... like the chicken and the egg.
Does the predisposition to usage have a natural link to suicide? Are people using to marijuana to medicate the underlying problems which lead to suicide? Or, is it the marijuana use which is solely responsible?
The deeper question which never really gets answered is why people would 'need' to get high every day. It is the escape from 'reality' (the 'reality' of one's own mind, that is) which should be our main concern.
We need to teach people that their memories will be there when they get back from being high. If there is a single message that we should be delivering to others, it is this. Memories are inescapable... unless you get amnesia. But then, you lose out on who you are.
I suppose we can say that we are failing to teach people who they are, largely because we can't agree on it ourselves in the age of the 'pluralistic' society. We have made everything an uncertainty.
Thus we live in a constant flux, and our fears come to overwhelm us.
