Where can a person who wants to go to school ,but has convictions for drugs on their record, find grants to go to colledge?

There are less chances because of the criminal record. There are no special grants for them, They have to apply for the same ones everyone else has except for the ones that will not pay to drug felons

Well first off depending on your territory you may contact the clemency board and see if you can get the conviction esponged (good luck on that one)
Best bet would just be student loans and Fannie May & Freddy Mac
