How do you know if your daughter is smoking marijuana?

Red, bloodshot eyes

Low, squinting eyes

Lethargy

Sleepiness

Slow speech or responses\

Skunky, marijuana smell

Marijuana paraphernalia (eg. Pipes, bongs, paper clips with resin on them, rolling papers, or lighters.)

In my opinion. however depending on how old your daughter is she should not be punished for marijuana use however do not condone it or allow her to. Just tell her you dont like it and if she does it you dont want her to smoke at home or at school/ on the weekdays.
