If you're really ou to get blitzed, in a red-eyed monster kinda way, TRY THIS.
This is one of the simplest things on Earth to build and I really suggest getting creative with the idea once you understand the physics. It is based on a the bong principle of sucking smoke through water, change the pressure and all of the smoke will go through the water.
Directions

So get a 2L or 1L plastic bottle Long and narrow is better.

then go get a bucket about the same height sa the bottle (don't panic when in doubt you can use your sink.

next scrounge up some tin-foil (for a bowl)

just a little side note - I use the bowl from a pipe. I drill a hole in the lid of the bottle just large enough for the bowl - so that it screws in air tight. -Note if it's not tight don't worry some plasticine or playdough around the bowl will seal it up tight.

Take a knife or scissors and cut the bottom of the bottle right at the base. make sure you cut it so the bottoms flat and the bottle will stand up on its own.

Next fill bucket with water, so when you place bottle in it the top of bottle is only an inch out of water.

Form bowl out of tinfoil. Use the tine of a fork or a safety pin to poke the holes (make sure its a safety pin because after a good round of buckets I wouldn't trust you or I with anything sharp.)

Put your contraption together - Bowl in top of bottle and bottle in water
How to use what you have built:

Rest bottle on bottom of bucket.

Pack a tasty little bowl of that fine, sweet Ganja.

I wouldn't be using any of that Tabacco shit in here.

This is where it gets tricky so read this before you try it. Use a lighter (difficult with matches - but not impossible) Hold the lighter to the bowl as you slowly raise it out of the water- Keep the lighter on it the whole time for maximum smoke. The smoke will fill the bottle - if not you really fuct up - cause even when this doesn't work it works. Once you have the bottle as far out of the water as it can be while still being in the water - Keep the bottom submerged. Now is where it is really hard - remove the bowl and place your mouth over the bottle. Try and keep the bottle as steady as possible to get full smoke from it. As you inhale push the bottle down in the water

Be ready, the smoke is forced into your lungs.
Yeah so that's how its done in CANADA
LEGALIZE IT!!!!
