I dont use, but if I didn't I would never tell wife/girlfriend. Why?
Cause everytime there's an argument, she'll blame your illegal drug use and roid rage.
He mother, sister, best friend will eventually find out about it - and they are little chatty cathy's.
Finally, there may come a day when you mess up and she is mad, and she may use the law against you. She sees a text on your phone and decides to scream in your face in the front yard... right then a police cruiser comes down the street - she says "he got drugs in the paint can in the garage!!!!"
Do you trust the emotional stability of your partner to keep you from jail? Keep it to yourself. never arm those around you with info to jail you.
