In an international survey conducted, 79% of respondents verified that their mental health has improved after they microdosed. “To date, most quantitative microdosing studies have excluded people with a history of mental illness, have not reported microdosing motivations, and no study has examined the sociodemographic and other correlates of microdosing as mental health and substance use therapies, nor the sociodemographic and other correlates of perceived improvements in mental health that people attribute to microdosing,” explains Toby Lea, the study author.
