    Toxicity

    PsychonautWiki

    The toxicity and long-term health effects of recreational 4-HO-EPT use do not seem to have been studied in any scientific context and the exact toxic dose is unknown. This is because 4-HO-EPT is a research chemical with very little history of human usage. Anecdotal evidence from people within the community who have tried 4-HO-EPT suggests that there are no negative health effects attributed to simply trying the it by itself at low to moderate doses and using it very sparingly (but nothing can be completely guaranteed). Independent research should always be done to ensure that a combination of two or more substances is safe before consumption. It is strongly recommended that one use harm reduction practices when using this substance.

    Effect Sentiment Distribution

    Confidence Distribution

    Each bar is the share of reports mentioning the effect; its whisker, and the band on the rows below, is the 95% interval: where the share could plausibly be with other reports of the same kind.

    Too few reports for bars: these effects come from 3 single-substance Erowid reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?
