Well 15 years is alot, but it seems theres always a new sort of pipe out there that he may not have. My friend brought over Clear Rolling Papers over and my buddy who is 30ish has been smoking a long time has never seen them.

Umm... at my loca headshop there is a pvc pipe type thing that is like 6 feet long lol. Possible longer it takes up a whole friggin wall.

Theres also these 'Blunt' pipes here too, im not sure how they work but I hear its alot like a blunt cause the pipe sucks out the ashes or somthin like that. They sell really well from what I hear.

Uhh I dunno peace.
