WITH reference to the article "Laurence 'let down' by mental health system", (Echo, October 22).
Just 34 words by Laurence's father, Malcolm tell the absolute truth about cannabis addicts.
"All Laurence's mental health problems came about through cannabis use," he said.
"He started using the drug at school and carried on when he went to university.
"The drug took over and led to schizophrenia."
These words should be printed out on sheets and circulated to every kind of school, so that pupils know from the outset the results of cannabis use.
I cannot recall such a brief collection of words saying so much of importance as these words by Malcolm Percival.
