Adderall (dl mixture) is just not the same. We know Adderall tends to exacerbate acne and some forms of dermatitis but we don't know how much. We don't know if the pupil effects contribute to driving incidents. We don't know if dry mouth from Adderall is worse for dental health than the dry mouth that some people get after heavy espresso or other stimulating substances, like pseudoephedrine. We don't think the risk of paranoid behavior is high but it is higher than coffee, of course.

And of course some not insignificant portion of the population can tolerate coffee or pseudoephedrine, but we're not too sure about Adderall. Schizophrenic, bipolar, OCD individuals, those with tics, tachycardia, etc, need to tread carefully with stimulants, even maybe sudafed.
