Pro-weed opinions are quite normal. I know a guy who is openly supportive of it that he will get very bitter with the government for putting those with a small amount of weed in prison and he has never complained about anyone "torturing" him.
Anti-war opinions have been popular since the start of the Iraqi war.
Frankly, I don't see how the CIA cares about you. And I'm not seeing as to why they should. You smoke pot and do nothing to put the country at threat. For them to bother to even come in contact with you (especially when the president himself told them to focus on more important things than people with a small amount of illegal substance for personal use) would require that you have actually done something. In which then, you being on the internet and announcing all of this is the best way to have them banging down your door.
