Table 1.

ED₅₀ values and 95% confidence intervals of stimulus substitution test drugs in groups of rats trained to discriminate 1.0 or 3.0 mg/kg 4-MMC (IP) from saline

Test Compound	ED₅₀ (mg/kg) (95% CI) in 1.0 mg/kg 4-MMC group	ED₅₀ (mg/kg) (95% CI) in 3.0 mg/kg 4-MMC group

4-MMC	0.18 (0.08–0.38)	0.50 (0.27–0.96)
MDPV	0.63 (0.17–1.08)	------
d-Amphetamine	0.48 (0.16–0.79)	------
(+)-Methamphetamine	------	------
Cocaine	0.92 (0.20–1.64)	------
MDMA	0.16 (0.07–0.36)	1.77 (1.00–3.17)^*
(+)-LSD	------	------
(+)-Fenfluramine	------	1.96 (0.40–3.52)

indicates a statistically significant difference between training groups
