Libtards parse, like you just did. Also, this was a 2103 interview, described by the FOX editor as a "rush transcript". His narrative may have changed, and that's OK.
Here's the entire read regarding MJ:
"Why are you more lenient on drug laws, sir?
PAUL: The main thing I've said is not to legalize them but not to incarcerate people for extended periods of time. So, I'm working with Senator Leahy. We have a bill on mandatory minimums.
There are people in jail for 37, 50, 45 years for nonviolent crimes. And that's a huge mistake. Or prisons are full of nonviolent criminals.
I don't want to encourage people to do it. I think even marijuana is a bad thing to do. I think it takes away your incentive to work and show up and do the things that you should be doing. I don't think it's a good idea.
I don't want to promote that but I also don't want to put people in jail who make the mistake. There are a lot of young people who do this and then later on in their 20s, they grow up and get married and they quit doing things like this, I don't want to put them in jail and ruin their lives.
Look, the last two presidents could conceivably have been put in jail for their drug use, and I really think, you know, look what would have happened, it would have ruined their lives. They got lucky, but a lot of poor kids, particularly in the inner city, don't get lucky. They don't have good attorneys, and they go to jail for these things and I think it's a big mistake.
WALLACE: Actually, it would be the last three presidents, but who is counting?"
I agree with every point he made including the negative effects both personally and community wise regarding chronic MJ use.
The social impact on Colorado is not looking too good.
