i used to get stoned before work all the time. one day i ate a cookie with 1 gram of kief baked into it. i was really fucked up i tell you what. i ate it on 1st break at 9 am, came up on it at around 11 am, went to lunch, came back, worked till like 2, then came off it around 3 pm; when it was time to go home. work was really fun that day, but im sure everyone knew i was blazed all to hell. it's cool though cause that job was easy as hell.
