How to fold a 'wrap' or 'bindle' of cocaine or speed

A drug dealer weighs the amount of Speed or Cocaine into the wrap. The wrap or bindle needs to be folded strategically to prevent spilling of this expensive recreational drug. Watch this video tutorial for a demonstration on how to fold a wrap or bindle for cocaine packaging. Tooth powder is used for the demonstration.

Nowadays most drug dealers use those little zip lock bags anyway, as they are not so susceptible to the damp air of a sweaty club or pocket.

How do I know how to do this? I mis-spent part of my youth. Once learned though, there are some skills never forgotten. I can still tie a bowline, something I learned over 30 years ago.
