To expand on this, when smoking thc, it will hit immediately, peak within minutes, and last generally about an hour or two. When consuming thc, it will start to kick in between 15-45mins later, peaking in intensity at 1.5-2.5 hours, staying there for about 2 hours, and will still be effective for up to 6 hours after consumption. If you take more within the ramp up period (between 1-3 hours) and end up taking too much, you could be very high for the next 3-4 hours.
