When it comes to controlling the potency of your cannabutter, there are a few factors to consider. On average, it's thought that only 60–90% of the THC or CBD will actually end up in the finished product. However, factoring in decarboxylation, how long you cook, and even which type of butter you use can all play a considerable role. So, in general, cannabutter has the potential to be fairly potent, and, of course, edibles also tend to hit much harder compared to smoking or vaping.
