I saw your post and I wanted to say that I am a recent college graduate, and not a mother or a teacher. I would just like to give you some insight on someone who has been in your child's shoes before. From what you have said it sounds like you have a bright child. I know that this probably heavily upset you, and that you may feel to blame or that you're failing as a parent, but none of this is true.
You did not mention what grade he is in, but it sounds like he has done some research and made a decision for himself and is "sticking to it." He just sounds hardheaded, like most high school boys. The thing you have to think about is just how you are frustrated with him for being close-minded and thinking that there is nothing wrong with marijuana- he is frustrated with you for being close-minded and thinking that everything is wrong with it.
I began smoking marijuana pretty steadily as a freshman in high school. I graduated top 5% of my class, took all college course AP classes, and even graduated a semester early without ever having to take early bird or summer classes. Marijuana was never a gateway drug for me, and I actually barely drank any alcohol at all during any of high school or college due to it.
My advise to you is to think about this: What is wrong with smoking marijuana in your opinion?
Then for every reason that you can think of, look it up and make sure that you are well educated and can back yourself up. If your son has smoked pot you can't tell him that it's a gateway drug and next month he's going to be shooting up heroin, because he's smart and knows that's not the truth. However, just like parents are sometimes old fashioned and close-minded about issues like alternative medicine or leisure drug use, so do potsmokers.
I was shoved a lot of statistics when I was a freshman. Health teachers were telling us that drugs would make you ugly and your hair and teeth fall out and give you mental disorders and heart problems. But there wasn't a lot of differentiation within the term "drugs". On the other end I was hearing from older kids at school you know, that there's absolutely nothing wrong with marijuana and that everything was a big conspiracy myth.
So I did my research as a freshman before I ever even picked up a pipe. I knew that smoking marijuana was less harmful to my health than tobacco or alcohol. However, that does not making smoking marijuana healthy for me, and I understand that, but it is noteworthy. And after I had tried it, it honestly helped me. I had been suffering from panic attacks and anxiety for years. My doctors had put me on medicine such as Paxil and Prozac that had literally left me suicidal and in danger of lists and lists of health problems. And with marijuana I just relaxed.
Here's something else you need to understand about smoking marijuana if you have not even been a user: You know how some people get off work and have a beer with their meal or maybe later into the evening? That is like my smoking. It's not like I was ever trying to get severely "messed up". But then, there are people who drink a fifth of vodka and are belligerent. You can get increasingly "higher" the more you smoke at a time. You are NEVER going to get that messed up. But I absolutely agree that if your son is going out and smoking 10 blunts, he is probably disabling himself from getting a good education. I however, functioned much better and much more concentrated and grounded after smoking a small amount of marijuana than with none in my system.
So I really do not smoke much anymore, I really don't have the desire or the need to. I will smoke a hitter if I can't eat or sleep, but this is around once every 3 months, if that. However, age-wise I am getting to a point in my life where I should be "settling down". So recently I've been thinking about what I would I do if I ever had a child and they smoked. Or what if they have friends I can tell smoke, or what if they have friends who have parents who knew I smoked and my child were to find out, what would I say? And this is what I think.
I think that if you smoke on a daily basis then at least one of your friends is probably dealing or growing marijuana. Since your child sounds younger I would say that probably one of his friends has a sibling who is dealing. Or I would hope so, or they're paying a ton of money. I would be angry if my child were selling weed or buying weed especially because a lot of high school kids are dumb and make transactions at places like gas stations, parking lots or banks.
And you need to explain to your son that while he doesn't think that there is anything wrong with SMOKING marijuana there are a lot of people that thing that there is, and it is illegal. And you need to explain to him that one slip up like that on his record could completely ruin his chances of getting scholarships, grants, jobs, careers, girlfriends whose dads are cops and can look that stuff up, etc., etc. For this same reason, you need to never call the cops on your son, because it could seriously injure his chances of employment or child custody or all types of things down the line that you never even think of in the heat of the moment.
You need to tell him that if he ever smokes commercial weed you will throw him out of the house. ;), but seriously. Commercial weed is cheaper and what a lot of beginners smoke. It is basically like brick packaged dirt weed, usually from Mexico that is very low grade. For whatever reason, sometimes, very rarely, it is laced with other drugs like PCP. I have never understood why, because I figure PCP has to be ridiculously more expensive than marijuana so why would any dealer do that, and I never believed it. But, there was a pregnant girl at my high school that smoked weed, (whole other issue), and it was laced with PCP and she inevitably lost her baby from this.
Marijuana does affect some people's abilities to drive. Like I said before, there are different levels of being high just as there are drunk. From experience, I would say that your average stoned driver would just yield excessively and drive under the speed limit. However, there are definitely people who cannot function a car in this condition. Beginner smokers would be less apt to know their abilities, and I would be very angry at my child for ever being in a car on a "roadie" where you smoke marijuana while driving with your friends. Or even being in the car with a stoned driver. I think those are perfectly reasonable things for a parent to get mad over. I also would get angry if my child ever had anything, as far as drugs or paraphernalia on them, especially in school. Remind your son that, at least in my state having drugs on you in a school zone is automatically a felony and easy grounds expulsion.
I know you're feeling that you only want the best for your child and that you want them to succeed. You also have to realize that smoking marijuana is really not that bad. It is just the fact that unfortunately, this country for whatever debatable reason weights getting high which is healthier than alcohol and tobacco use worse that battery, assault, and even sometimes rape depending on the drug. If you look at what classifies as a misdomeanor/felony and their classes it's honestly revolting. Above all talk and make sure that the communication is open and loving. Don't let him answer "I don't know" or "I just do" ask him what he likes about it. And that is isn't just a wrong group of kids who are just hellions. Ask him what other hobbies they do, or he does. Ask him if they do well in school, how he is doing. You may get very surprised. There were definitely "bad" kids that smoked marijuana at my high school, but that doesn't mean I associated with them just because I smoked marijuana. And I did have some friends who did not do well in school and got into some bad stuff after high school, and that's life. That doesn't mean that I was not educated enough or taught well enough to not let anyone hold me back, and your son might be that way too, and he may just like to get high.
But you do have to be so careful. I would say the only time it is acceptable is in a house where the homeowner is allowing of it. Because it is too much of a risk to be driving around doing it, and definitely doing it at school. A couple of his friends will get caught at some point & he'll see.
