There's no denying that the process to make cannabutter can potentially be a long one. Typically, the task takes a minimum of 3 hours, or can even stretch out to around 12 hours. But that doesn't mean you have to stand there for this amount of time. A stir every 30 minutes until the butter is infused will be adequate enough. As mentioned, if you're new to the task, it might take a little fine-tuning and experimentation to get the process down to a T.
