A mother of a friend may be sympathetic and let you live at their house. Dip out of the parents' house for 2-6 months while still going to school and the parents will be begging to have you back, with new terms and conditions. If they don't want you back then they aren't worth the energy.
Well, I am going to give you two suggestions, or one suggestion and one piece advise. One, shave your head in protest! They can still give you a piss test but wtf you are already in trouble so what does it matter. It will also give you a great story to tell everyone at school. Now for my suggestion. If you are living at home I am going to assume you are underage. So, just give it up for a while. You can always smoke weed when you get to college, just like most people. I personally did not start smoking until I was in my thirties. If you just quit for a while your parents will be so confused, they will not know if you really gave it up or not. You might still have to take the piss test but then they will be like, "how are you passing this test!" It will be fun.
Haha shaving your hair is a good idea... How old are you? You said they're going to hair test you "for years", I highly doubt that. I've been caught twice (I'm 17) and my mom said she would drug test me, have me see a psychiatrist, etc and it never happened. Two options from me as well: 1) Continue to smoke, but try as hard as you can not to get caught. Think ahead, hide evidence. Act like you live with the police. If you don't get caught for a while, they will think you stopped and they wont check up on you as much. (this is what I did) 2) Continue to smoke & not give a hell what they say. Depending on how evil they are, ask yourself what is the absolute WORST they could do to you, and could you handle it. Friends of mine did this, and their parents end up giving up on the situation because they can't win. (i'm too chicken to do this)
how are they gonna get the folicle out if you keep shavin it? just shave your whole body and keep smokin weed. tell your parents to suck their fingers and keep shoving weed into your potsmoker. DO IT
In my high school years marijuana caused a lot of trouble in my family. My brother got expelled for selling it and then a few years later my parents constantly caught me UI or found my stuff. If you look at it from their POV, they raised two kids, one who sold, then one who used. When I was 17, I quit until I could afford to move out. I sat down and talked to them about it, placed facts right under their noses, but they still wouldn't change. Sit down and have a talk with your parents about it. Try to persuade them. Give them the real facts. Have them understand you're not using it just to get fucked up, but that you've made an educated responsible decision. If they won't change, then quit till you can move out or go to college. I tried persuading my parents all through high school and they sure didn't change their minds. They understood the facts but still didn't want me using it. You may believe them to be oppressive devil nazis, but give it a few years then look back. You'll see what I mean. edit - To all the people telling him to shave his head and not give a fuck what his parent say, don't be ridiculous. If his parents sent him to a psychologist and are going to hair test him for years, what the hell do you think they're going to do if he shaves his head in protest? I highly doubt that'll change their minds and allow him to smoke. If anything, it'll make them even more adamant about not letting him smoke. My $0.02.
That really sucks big time. I say have one last kick ass high. Then quit for a couple of months. and get your parents trust back.
