BBC News has a 15 minute documentary about people who take regular tiny doses of psychedelics drugs to deal with mental health issues, improve productivity, or just better appreciate what life has to offer.
From YouTube description:
Microdosing is when you take a tiny amount of psychedelic drugs – LSD or magic mushrooms usually – as part of your ordinary day. The drugs are illegal, and there is no medical evidence to say what the benefits or harms of it may be. But a small community of people in the UK are doing it anyway, and say it’s improving their lives. Some say it aids creativity and concentration and others argue it helps with their mental health problems. BBC Reporter Catrin Nye has been meeting the people that do it.
Here's my interview with Ayelet Waldman, who microdosed for a month and wrote a book about it called A Really Good Day.
