My child who has admittedly used and does still occasionally smoke weed leaves the odd pencil lying around. It is not the plastic clutch pencil with the lead refills - but coloured pencil crayons which all have the point snapped off, whenever one is found around the house. I understand smoking / snorting being done through pens, but what on earth would an old fashioned pencil crayon be used for - with the tip broken ? Am I over analyzing or is there a use for these with weed or other drugs ? :-(
