Outside of maybe DPRK and France (I kid but they do take their speeding seriously) speeding is a civil crime. Speeding by some large amount (20+ in most of the US) can be a misdemeanor at the cop's discretion. You'd have to do something far beyond speeding, like provoke a police chase or something, to catch a felony. I'm unaware of any state where you can catch a felony charge from speeding and only speeding (delusional prosecutors trying to charge people with things that have zero hope of sticking notwithstanding).

Simple possession of a federally classified CDS I (which all psychotropic substance are) is a felony in almost ALL 50 states. It may be a misdemeanor in a few, but that is not ‘most’ states.
