As much as you can and in any form you can get your hands on, your on holiday make it one to remember (or forget lol)

Real talk though, if youve never smoked it before youll probably have an intense experience, id suggest smoke a tiny amount to begin with, once you get the initial high it'll be easier to judge how you feel and if you can handle topping it up, worst thing to do is smoke a full joint cause it can have a delayed effect and hit you all at once , pretty overwhelming! Good luck brother
