Methamphetamine, the illegal and illicit drug, as well as cocaine, heroin, and others drugs have been tried in many deadly ways:
Body Stuffer: eats a wrapped amount of drug quickly, usually to evade law authorities
Body Packer: eats carefully wrapped amounts of drugs in multiple packets to carry or be the "mule" – items such as aluminum foil packets, baggies, condoms – all loaded with drugs. Packers may eat these, surgically embed packets, or place them rectally to transport, known as "keistered."
The "parachute" technique involves ingesting an amount of illicit drug in a wrapper, that with time, slowly unwraps, or unravels to release its poison in a "slower" or "controlled" fashion.
OF COURSE, BODYPACKERS, BODYSTUFFERS, AND BODYPARACHUTERS ALL HAVE SIGNIFICANT RISK FOR SUDDEN BURSTS OF DRUG OR POISON BEING RELEASED, THEREBY CAUSING SIGNIFICANT TOXICITY AND DEATH.
