Long-term effects remain largely undetermined.[4][6] In a study examining the qualitative reports of 278 microdosers the researchers found that there were mixed results among users.[11] Some users experienced positive effects such as improved mood and increased focus, while other users experienced negative effects such as physiological discomfort and anxiety.[11] More recent studies have indicated increasingly positive results in the categories of: improved mood, improved focus, and social enhancement.[4][12][13][14][15][16]<br />In one of the only double-blind, randomized studies to date, those given microdoses of LSD did not perform better than those given the placebo on cognitive tasks.[7] This study did not have any conclusive evidence on whether or not microdosing with LSD has any therapeutic effects for those suffering from anxiety or depressive disorders since all participants were healthy at the time of the study.[7] This study analyzed users who answered mood questionnaires and performed behavioral tests after taking a range of microdoses from 0-26 ug of LSD.[7] The only changes in function that this study saw were a decrease in how the users rated the positivity of images that had positive emotional content and an increase in their vigor, determined behaviorally, when compared to those who received the placebo.[7]<br />Another randomized, double-blind study examined the effect of microdosing of LSD on the perception of time.[17] Participants were either administered 5, 10 and 20 µg of LSD and assessed using a temporal reproduction task and self-report measures.[17] The study showed no significant changes in self-report scores of perception, mental activity, or concentration among the three groups.[17] Despite larger reported drug effects of temporal perception, there were not any significant effects of the drug.[17]<br /><br />An open-label natural e
