I've already stated this several times. Let me copy and paste myself here.
Apparently you need to step up the concentration of your weed if it has no effect on you anymore. Going off what you just stated, you're an addict. You perceive yourself as more aware, when you aren't. Weed is doing nothing for you other than giving you false perceptions. Driving stoned is just as dangerous as driving drunk. Don't tell me that you think weed isn't bad for your lungs or heart.
I just don't see the point in doing it, I drink, on occasion, but then again I don't have any children to look after. I'm straight right now, and I already know I'm more responsible than you are if you're getting stoned with kids in the house. Time to grow up and stop wasting money on that shit.
