Some say LSD produces hallucinations and lowers inhibitions. Others believe it makes people more capable, efficient and creative. In Silicon Valley, many even say LSD can be a tool for self-improvement. More and more people in Germany are discovering what’s known as microdosing in order to be the best they can be. Every three days, a 28-year-old man takes his LSD out of the freezer and slowly lets the ice cube containing the drug melt on his tongue. He’s taking ten micrograms of LSD. He learned about it online and says the allegedly harmless dose makes him feel more focused, productive and empathetic. The trend from Silicon Valley is an open secret at many innovative start-up companies. Paul Austin, who’s something of an LSD guru in Silicon Valley says, "People who responsibly take psychedelic drugs in microdoses will rule the job markets of the future.” But others are sceptical. They warn about self-medication, saying there’s no way of knowing the LSD’s concentration. If things go wrong, psychoses and persistent sensory disorders may follow. But this documentary shows there is more to it. After years of being locked away with the poisons, 'acid' is back and a hit among a new generation of researchers and doctors. Some say it can ease depression and anxiety. So is LSD good medicine? This film explores the past and present of a drug that was legal until the 1960s and was used by doctors to treat the blues and alcohol addiction.
