I'm new here, help with weed

I've been thinking about smoking weed for a while now. I already had this opportunity when I was 14 years old, but I refused. But now I feel like it again and I don't know where to get it, especially since it's illegal in my country. I also wanted to know some tips on how to 'disguise' yourself after smoking weed.

EDIT: Hiii guys! Tysm for all the tips and advices. After reading a lot and researching as well, I decided that it is best to wait until my brain is fully developed (25 years old). But still, tysm u all!
