I saw that no one has replied to you, hopefully you are checking in and will get your answer.
That is what people mean by parachuting, its a good way to get a substance into your body orally and it can remove some of the nasty taste some drugs have. Also crushed pills can be put into the paper so that it is absorbed faster, due to the greater surface area, than taking the pill as it was initially intended. Im not saying to do this however lol
Just put your stuff in the middle of the sheet of paper, twist it like a candy wrapper, and then rip off the excess, just dip it in a little water to make it go down the gullet easier and chug back with something tasty!
