Letter to the Editor

Psychedelic drugs reliably trigger experiences that closely resemble synaesthesia (Luke and Terhune 2013), a condition in which inducer stimuli will reliably and automatically elicit atypical concurrent experiences (Ward 2013). These transient episodes are considered controversial because they do not meet behavioural diagnostic criteria for developmental synaesthesia (Terhune et al. 2016). However, if these behavioural markers are attributable to the consolidation of synaesthetic associations over time (Terhune et al. 2016), they should be observed in cases of acquired synaesthesia. Here we report a case of drug-induced acquired synaesthesia (LW) that meets standard diagnostic criteria for developmental synaesthesia.

LW is a 29-year-old male who reports continuously experiencing multiple forms of synaesthesia for over 7 years since ingesting approximately 70–150 mg of 2,5-dimethoxy-4-bromophenethylamine (2C-B) (Papaseit et al. 2018), which greatly exceeds the normal dosage (12–24 mg)...
