I have done twice (God only knows why I did it the second time) but the first time should have been enough. I never smoked it though. I ate the seeds and smoked one joint to kick it in. I was f**ked up for 2 ½ days strait and it screwed with my vision for about a week after. I researched it after that and found that I really shouldnâ??t have messed with it. Most people over dose on it cause it only takes a little to work and when they od it does one of two things. You go blind permanently, die or both! Donâ??t mess with it. Seriously. But if you are anything like I am. (fearless/stupid) youâ??ll do it anyways. If you do, make sure you under estimate the dose. Start with no more than ½ tsp of seeds and chew them up real good before swallowing. Smokin a dove (joint) helps kick in the buzz as I remember. Above all be careful!
