It should not be surprising that adults with ADHD are statistically more likely to commit crimes.
We already know that:
1. A majority of criminals have learning issues, to a point that prisons have distinctly lower literacy and education rates than the rest of the country.
2. ADHD makes it harder for you to learn things, especially the harsher forms of ADHD, and also often makes you hyperactive (thus the name, hyperactivity disorder). Thus, it seems likely that the people who have it are more likely to commit crimes if left untreated.
Does this mean that the state should have the power to force people to take the medicine? Certainly not.
But:
1. People who have the disorder (a fraction of those having attention issues, and probably a fraction of those diagnosed), should be able to have it prescibed and paid by their medical insurance or whoever pays for their medical treatment. In the specific case of people with actual ADHD these medicines are a medical treatment just like anti-depressants with the chronically depressed and antipsychotics with those who require them.
2. Since all drugs should be legal, those having attention issues should have access to these drugs.
3. In general, nootropic (brain enhancement) drugs should be legal.
Et ceterum censeo FDA delenda essem.
