One hundred bespoke artworks have been created to make you wonder if you smoked way more than you thought – or if the illusions just make you feel like you did. In this trippy book, there are new designs and classic optical illusions that have been redesigned with a weed theme, but with the psychology and science behind them still intact. From pulsating patterns to bizarrely impossible shapes – not to mention spliffs that you could have sworn were longer a minute ago – this book will make your brain tingle before it blows your mind. Isn't that dope?
