Bro just emphasize that your not in any danger and you've been joosing for years so your demeanor towards her proves she's not in any danger of you fresking on her. Tell her its not a drug like heroin, sports athletes use them all the time and these are guys who are in the best shape in the world both mentally and physicslly.
Give her some time to cool down before talking to her and then try to talk it out. Why was she going through your phone in the first place? Is a question I may ask somewhere in that conversation (without trying to point fingers because that will just fire her up even more)
