Greenhead Clinic in Kata is a subdued, comfortable space with high ceilings and tall easy chairs to sit in and discuss cannabis; after all, there is a Thai traditional medical practitioner on duty in the daytime hours. The practitioner is there to answer your questions and guide you in your purchase decisions. She is there to help you find the flower strain(s) that are right for you. The clinic is in a great shopping district just of the main road in Kata. Greenhead prides itself on offering cannabis of medicinal quality only. Though they are big on applications of current research on cannabis and health, the inventory shows that they have no intention of taking the fun out of consuming cannabis. Their collection of bongs is extensive and includes volcanoes, gas masks and even a Star Wars mask bong. It’s a large space with comfortable easy chairs to sit in and talk about cannabis. Staff is 5-star in every way: smart, friendly and patient.
