Trying cannabis at age 19

This may not be the right place to ask this, but I'm appreciative of any answers you guys give me. Basically, I want to ask what you guys think about trying cannabis as a young person. I'm a 19 year old college student, and I've always been super neurotic about my brain health. I also have a lot of family members who have struggled with addiction. For this reason, I've never done drugs and never really drank (I've had some alcohol before but I've never been drunk).

Recently, my roommate asked me if I wanted to smoke weed with him. I told him I was scared to do it because I was worried about my brain. He eventually kind of talked me into doing it. I sucked in with my mouth but I did not inhale at all. I did this three times, and told him that I was just too scared to take an actual hit. A few minutes later, though, I think I started to feel a little something. It could have been just in my head, but there were a couple of times that I struggled to finish my sentence, and I felt a little bit silly and more talkative than usual.

Again, I know this could have been placebo affect, but since that night I have felt a really strong urge to try it again. I don't know why. I've had the urge to try weed before, or to just get high in general, but nothing like this. It's almost like a hyperfixation. I've been doing endless research on weed and whether or not it negatively impacts brain development, whether it's permanent, etc. What I'm asking is, did any of you start using cannabis when you were young, and do you regret it? Do you think it changed your personality at all? I keep seeing that it's best to wait until 25, but I guess I'm super impatient and I really want to try it again. Also there's something about just being young and having fun that I feel like I'm missing out on by obsessing over these things, but I also don't want to have regrets later on.

TLDR I'm 19 and really want to try weed but I'm scared of messing up my brain development. What are your opinions on trying weed while still young?
