I would not eat weed on a day that I had to go in to work.
Especially if I had a panic attack last time I smoked it. Oral consumption can be fickel, too little or too much other food in your tummy and not much happens. A little too much weed and your blasted and various levels of paranoia can develop (a lot worse than smoking).
That said a little excess can be enjoyable as well.
I would use 1/2 gram in a firecracker, eat it on an empty stomach, preferably early in the day, so that you have the whole day to enjoy it and recover from it
Don't smoke with it until 1.5 hrs after consumption,so you can appreciate the oral buzz.
Good luck, and let us know how you did.
