The drug failed to substitute for LSD in rodent drug discrimination tests, with a maximum of 25 or 50% LSD-appropriate responding at the highest assessed dose.^[1][4][5] Unlike other 6-substituted lysergamides, PHENETH-LAD was not assessed at the serotonin receptors.^[1][5] According to Alexander Shulgin in his book TiHKAL (Tryptamines I Have Known and Loved), PHENETH-LAD produced no effects in humans at a dose of 500 μg.^[3] He has specified the potentially active dose as being >350 μg and its hallucinogenic potency being less than 30% of that of LSD.^[2][6]

PHENETH-LAD was first described in the scientific literature by Andrew Joseph Hoffman of the lab of David E. Nichols at Purdue University in 1985.^[4] Its effects in humans were first described by Shulgin by 1994.^[6][3]
