When cannabis is eaten,
THC and the other cannabinoids compounds that create the high enter the blood stream via the digestive system. This is a slower and less predictable process than when cannabis is smoked. Whereas smoking produces an almost instant high, the effects of eating can take anywhere between 15 and 90 minutes to arrive. The time taken for the high to come on is affected by the way the food is prepared, the ingredients used and the amount of food passing through the digestive system at the time.
Soon after being swallowed, the cannibinated food reaches your stomach, it is churned around in a mixture of acid and enzymes. Now liquefied, the food is squirted into the intestines. Here, more enzymes and bile work on the fat in the food and the cannabinoids are absorbed, through the intestinal walls, into the blood stream.
Once in the blood stream, the psychoative compounds are on a high speed tube ride to your brain. Usually, within 45 minutes of swallowing, some of the cannabinoids will have reached the neural receptors in the brain and the user will begin to notice the effects. As more and more of the chemicals make there way through the system, the user will become stoned.
