It is always your choice. Only you know your situation and circumstances.
But, I will say this: The longer you are IN, the harder it can be to extricate yourself out.
Also, dont think for a moment that those "edgy witnesses" who you hang out with and do fun activities together, will not take a sudden guilt-induced turn one day and rat you all out!. It happens.
Take care. It is more rewarding to live an honest life than a fringe life....
