In his 1984 top 10 pop hit “I Want a New Drug,” Huey Lewis lays out his criteria for the perfect drug: That rare, no side-effects high that won’t make him do a series of things — make him sick, crash his car, feel three-feet thick, hurt his head, make his mouth too dry, or his eyes too red. It won’t make him nervous; it won’t spill; it doesn’t cost too much; it doesn’t come in a pill. It won’t keep him up all night, or make him sleep all day. It does what it should, he imagines. It won’t make him feel too bad — or too good, either.
