Alternative method: make one of the two holes bigger

A Lung / Rats Tail
Cut an entire bottle off (ex: cola...) in the middle
Tape the open end of a plastic bag to the top of the bottle using sticky tape.
Pierce the stopper with a tiny hole (to put a joint)
Now push the bag all the way into the bottle so that there is as little air as possible actually contained in the bottle.
Roll a joint (european style), put it in the hole, then light
Now, pull the bag, until it is completely outside of the bottle.
The bottle should now be full of marijuana smoke
Now remove the stopper, then aspire
