Wall St. Guys: How common is taking narcotics in the field of finance?

Sorry I know this is a weird post and you’re probably thinking “nice try NYPD” or “None of your good damn business”. Which is fair. But I just saw this video on YouTube from this Channel called “Good Work”. And there was a video about Wall Street guys doing drugs.

But I want to know really how it is. Relax, I’m just a Senior Software Engineer working in Finance and even I need some green stuff and Red Bull every now and then to cope with the amount of stress, meetings, deadlines, annoying clients, technical difficulties, pressure etc.

But I would like to know from your personal experience (however much you wanna share).
