For sure. I take adderall and have an incredibly high metabolism to the point of needing to add 1500 calories per day in protein shakes to stay at a healthy weigh. 7.5mg (15mg in half) is my usual dosage, but it's strong enough to fill me with the energy you'd expect someone on a high dosage to have. When I talk a full pill, it completely screws me over. Others can take 30mg and be completely fine.
