The inclusive {ital S}-wave charmonium production rates in {ital B} decays are considered using the Bodwin-Braaten-Lepage approach, including the relativistic corrections and the color-octet mechanism suggested as a possible solution to the {psi}{prime} puzzle at the Fermilab Tevatron. We first consider relativistic and radiative corrections to {ital J}/{psi}{r_arrow}{ital e}{sup +}{ital e}{sup {minus}} and {ital J}/{psi}{r_arrow} light hadrons (LH{close_quote}s), in order to determine two nonperturbative parameters, {l_angle}{ital J}/{psi}{parallel}{ital O}{sub 1}({sup 3}{ital S}{sub 1}){parallel}{ital J}/{psi}{r_angle}, {l_angle}{ital J}/{psi}{parallel}{ital P}{sub 1}({sup 3}{ital S}{sub 1}){parallel}{ital J}/{psi}{r_angle}, in the factorization formulas for these decays. Using these two matrix elements and including the color-octet {ital c{bar c}}({sup 3}{ital S}{sub 1}) state contribution, we get a moderate increase in the decay rates for {ital B} decays into {ital J}/{psi} (or {psi}{prime})+{ital X}. Our results {ital B}({ital B}{r_arrow}{ital J}/{psi} (or {psi}{prime})+{ital X})=0.58 (0.23){percent} for {ital M}{sub {ital b}}=5.3 GeV get closer to the recent CLEO data. As a by-product, we prefer a larger decay rate for {eta}{sub {ital c}}{r_arrow}LH compared to the present data. {copyright} {ital 1996 The American Physical Society.}
