Replying to Shrooms while on probation?

So a couple months ago my roommates and I got nailed for possession (less than 1g between three of us) and now we are all on probation and are drug tested monthly. We aren't supposed to drink alcohol or do any drugs obviously. However, the tests aren't random and I've read online shrooms don't show up in the tests that the court uses and they only stay in your system for less than 20 hours. I'm just wondering would you guys be sketched to try a new drug while on probation even if you'd probably get away with it? Share your thoughts.
