Stallion Books #213 Reefer Club by Luke Roberts 1953

Pretty Solid Very Good + Condition Copy

The original edition was published under the Uni Books imprint (No. 49) rather than Stallion Books, though your first message referenced a blog listing showing it also circulated among the same family of "digest" sleaze paperback lines from that era (Stallion, Fiesta, Venus, Carnival Books, etc.) — publishers reissued and relabeled these cheap paperbacks under different imprint names, so you may have a "Stallion Books" reissue/reprint numbered 213

The cover art, per a library archive description, features a blonde woman smoking a marijuana cigarette in the foreground, with additional images of women lounging and smoking — typical "good girl art" (GGA) exploitation cover style.
