Ex. 1

"A happy card is a greeting card that is usually saturated in a narcotic. So you get -- it's my birthday. They'll saturate -- they'll liquefy methamphetamine, say an ounce of methamphetamine, in a small amount of water and spray it onto a card, or saturate it in some fashion, let it dry, write on the card, and send it in. It's odorless, colorless, and it gets right in. It can also contain heroin, LSD, cocaine."

Rene 'Boxer' Enriquez, USA v. Jaimez et al, September 12, 2018.
