Unlike smoking cannabis, where cannabinoids enter the body through the lungs, edibles help infiltrate cannabinoids into the system through the gastrointestinal tract. The result is a high that is much more intense and having a long lasting effect.
Most often than not, edibles take longer period to start working in the body — between 30 and 60 minutes. But it is worth noting that, the effects can last from 4 to 12 hours depending on the amount taken.
Starters or people with smaller frames might find 10 milligrams too potent, and therefore might be better off starting with 5 milligrams.
Note that a single chocolate bar can contain as much as 100 milligrams of THC
