Sirius’ patented zaniness, a little forced from time to time, makes for a not-altogether-serious disquisition on the intersection of the rock-star lifestyle and recreational substance abuse. So what? The text, mostly articles accompanied by lists (of rock stars on coke, rock stars on ecstasy, etc.), skips right along. Sirius’ “rankings” in various categories occasionally owe more to name-checking for big stars than any sort of logic, but he does cover a lot of ground entertainingly. Certain names get dropped in relation to more than one drug. Keith Richards and the Grateful Dead, for instance, score consistently, and Sirius manages to place James Brown and Charlie Daniels cheek-by-jowl in a list of rock stars against drugs—closer than they ever came corporeally or musically. Some rankings seem obvious. Number one rock star on weed? Bob Marley, for whose religion ganja is, of course, a sacrament. Also on deck: Nixon’s war on drugs, Sir Paul McCartney’s weed-ophilia, and more pithy hip-hop-star anecdotes than you could shake a spliff at. Good, clean fun.
