my daughters father started with pot at the age of 16,he died at the age of 32 from a herion overdose.im not saying pot leads on to stronger things very time but it did for him.when i go back to my hometown in england i often see one of his old friends wandering the streets,he is about 40 now,for the last 10 years he has wandered the streets suffering from pot induced physcosis,so no i dont take pot lightly.
