Reverse Paranoia

Should I smoke weed?

I found out yesterday that a few friends/people I know smoke weed (cannabis)..
I don’t think it is that harmful if you don’t do it too often, but I know it can cause brain damage & paranoia.
Also, I would not like to do it at school or skip lessons to do it, or do it just to fit in, but maybe for parties or something occasionally as it seems like fun.
Could this be harmful?
I am 13.
I do pretty well in school and do not want to ruin this, aswell.
Will it make me dumb?
I realise it is addictive, but I wouldn’t do it often.

No it will rot your brain, then you will end up on harder drugs.
