Drug Rehabilitation that works

Not your typical church hymns with organ music…here is how the Christians at Angelus Temple worship on Easter Sunday! www.angelustemple.org We were visiting from Pennsylvania and were blown away by the amazing worship and teaching!

I’m fairly concerned that one of my family members is on crystal meth now. I know its not my mother-in-laws drugs, because she only does ketamine, whippits, and nyquil.
How do I find out whose drugs they are without confronting or embarassing anyone? Or should I just keep the meth and use it/sell it?

Why cant my family go back to the simpler times of hiding airplane bottles of liquor around the house for Easter?
