Legal in all 50 states, this entertaining, informative, and whimsically illustrated guide covers 4,000 years of weed and its significance-psychoactive, cultural, medical, sexual, and more-in just 22 pages and with 20 scratch-&-sniff scents. From the science behind the munchies to the botanical link between weed and beer; from weed's sexual upsides to its (literal) sexual downsides; from Tupac to Shakespeare to why weed makes music sound better: This book may just be the greatest-ever gift for anyone from the cannabis connoisseur to the cannabis curious.
