Evil special interests?

One of my special interests is recreational drugs. I'm big on harm reduction, have tried 35+ different substances. I'm not addicted to anything besides caffeine and nicotine, and I've only been honest with one doctor about this. They refused to refer me to anywhere except for rehab centers and he stopped all my prescriptions, which I think anyone could've seen coming

I even called a few rehabs and had intake interviews with them where they told me I don't qualify for their services

Also people who aren't medical professionals, who do drugs in the most irresponsible ways, will try and lecture me about them, I'm assuming because they see me as a child and think I don't know what I'm doing. They don't seem to realize a lot of their problems with substance abuse aren't inherent to using the substance, it's their own lack of education and preparation causing problems

What interests do you guys have that get you in trouble/you can't be honest about?
