Why won't my parents let me get a face tattoo?

"I smoke weed and drink all the time so I'm basically and adult."
That does not make you an adult.
You're 13, far from being one.
You should be a teen while you can be, it's too soon to make decisions about your body and life changes.
"I wish my parents would stop being so controlling"
They're trying to protect you from drugs and weed and want the best for you. They may think that your boyfriend will be a bad influence on you, which may be why they don't like him.
13 is a young age for a teen and most of them don't know what they want in life exactly. Look at it like this, you get the tattoo, you break up with your bf, his name is on your face forever.\
Look at Courtney Stodden. She was 17 and thought dating a 51 year old was a good idea, which wasn't because they ended their relationship.
The point is I think you should get a little more mature in life and older before you decide what exactly you want in life. Live your teen years while you can, don't rush into adulthood.
