Let me tell you of my experience with something similar to 'pot brownies'.
So it was the end of 2010 and I was heading to tropical north queensland for a holiday. I had made some nice cannabis infused butter a while ago and wanted to use the rest of it before I left. Well I thought lets make some scrambled eggs in pot butter.
My scrambled eggs ended up as green buttery buttery eggs on toast. I would have used around 100ml of this butter to scramble 4 eggs. Wow I felt a little queesy after all that fat.
So I took the train into the airport and by the time I had arrived it was starting to kick in. The dude at the checkout looked at me and probably saw my glazed eyes.. He knew, I could tell. Or was it the epic paranoia that kicks in when you are at an airport having eaten an epic amount of canna-butter and worrying that you will be rejected from the flight and miss your holiday if you appear too drugged.
I stayed as cool as one can in this situation.
Now for takeoff. Wow, So I was on the plane, buzzing like buzz aldron. I clicked the seatbelt into place and put those crappy headphones they give you for free in my ears. The plane coasted down the runway and took off. It was like being launched into space. An amazing feeling. By this time I had an epic body stone and was just happy to be on my way.
Arrival. So I arrived to meet my friends after two and a half hours of flying time. I was stoned for the rest of that day and copped abit of shit because they were all jealous and in disbelief at finding their stoned companion walk out of the bushes from shuttle bus.
Experience overall:
If I were afraid of flying I would not for one second consider this. I love planes, they are amazing, and for me being a passenger in one is an honour. However what an experience! Just beware of potential airport paranoia.
