ok, you have two types of pipes. a metal one, and glass one.

metal bowls are just a what look like a tiny bowl with a little stick coming out of it. With that, just tear up your weed.. stick it in the bowl part, light it.. and inhale.. hold for a few seconds.. exhale.

Glass bowls have a bowl looking part, and something that looks like a stick coming out of it. Glass bowls also have something called a carb hole. The carb is a little hole in the side of the Bowl part. You tear up your weed once again, put it in the bowl part, place your thumb over the hole on the side of the bowl, the bowl resting in your palm, light it.. inhale, take your thumb off the carb and keep inhaling, you should feel the smoke enter you. Hold it in for a few seconds.. then release.. repeat untill all the weed has turned grayish white. Then empty.

You can make pipes out of soda cans, bottles, even apples.. do a google search... you'll be a amazed how many helpful sites are out there..

GOOD LUCK!
