Firstly, review the total amount of THC or CBD in the edibles, determined by the potency of the Cannabis used or concentrate used. Next, the per-serving dosage displayed by the calculator shows the amount of THC or CBD per serving so that you know the active compounds you'll consume with each serving. As a precaution, confirm whether the dosage per serving reflects your desired potency level. In other words, for a mild effect, try 5-10 mg of THC. For stronger effects, use a higher dose of 20-30 mg. Keep in mind your tolerance to Cannabis, which depends on whether your body has been exposed to Cannabis before and hence conditioned to its effects on mind and body. Beginners would do well to initiate with smaller dosages to see how their body reacts before gradually increasing their intake.
