I do see attitudes changing with the College Grads about Marijuana use.

They're rationalization is that, "The laws are rapidly changing and now getting less strict by the day"

I then ask them if they'd be willing to give up their 2nd amendment rights forever.

They'd respond in the negative.

I then remind them that use of marijuana, (either with a State Medical Card or by legal use via State law), will automatically make that user a prohibited possessor of firearms per Federal Law.

This usually changes their attitudes.
