Am I allowed to carry weed? If so how much? And as a carry on or what?

I wouldn't

I believe that airports are governed by Federal law, and marijuana is still not legal under Federal law.

I got by with my pen and 2 cartridges they didn't do nothing but weed i wouldn't

No

If you are flying, no.

Federally No! "I've heard small amounts going from legal state to legal state might be okay" but that's not law...
