louisiana, do it behind her back. It's seriously not that hard to be low key about this shit if you try.
If she ever caught you using again and found your stash then you could tell her she doesn't know jack shit about what she's talking about and she's a hypocritical bitch. Man up.
That's my opinion. If you want to do something and you don't feel it's wrong even though the public perception of it is massively distorted then go for it. Your wife guilt tripping you or going off on you is lame especially because she doesn't have a clue.
