I'm open about it but in a way that allows for plausible deniability. I will refer to prior use without specific dates, and I am pretty selective about the kinds of things I'll openly admit to (psychedelics, sometimes ketamine) vs. the types of things that I'm more private about. I am very open about my history with heroin before getting clean in 2008. Part of the reason for disclosing that is because I want to push back against stigma and show that people can get clean and contribute to society in a meaningful way. I'm a licensed clinical professional with a couple of graduate degrees which helps to show that I'm a respectable professional. I don't know if I'd be as open if I didn't have the years of working as a clinician/graduate education. That said, I'm open about it in order to make it easier for others to be open too.
