Your parents shouldn't. Because that's their job to make sure dumbass teens like you don't do stuff that will get them killed. You sell weed, someone is going to try to rip you off... and if you are lucky, they don't do it as a home invasion and put bullets in you and your family. You might as well try to convince your parents to let you prostitute yourself in Costa Rica where the age of consent is 15 and so is prostitution.
When you turn 18 and are legally an adult, you can mess up your life all you want. Wait until then.
