Let's say you use a 0.5 g dab which has a THC content of 70% (most dabs are either 1-gram or 0.5 g). The wax has 0.35 g (350 mg of THC), but you could lose up to one-third of it when vaporizing. If this happens, you’ll end up with roughly 235 mg of THC per hit (if you can finish the whole dab in one hit).
Someone without a THC tolerance will be completely satisfied with a 5mg dose, total.
Thats 47 doses out of the 236mg the stoner _absorbed_
