How can I get a buzz without drinking alcohol?

I want to loosen up and relax more around women and in general. So how can I do that without having to drink? Like I would want to go out but relax and I can’t drink any alcohol to relax me because that is an unhealthy way to relax. Any other suggestions to get a buzz or any healthy drinks and food to eat that will get me relaxed and feeling good without having to drink beer or liquor? Therefore, I can be sober at the same time.
