I honestly wish that were that case. I wish he wanted to be better, but I can't do anything to change him. For the record, he's my step father. I had to live with them for a while, it was terrible. Angry is an understatement. He's narcissistic, post-violent, and... scary. I really do prefer it when he smokes because he's calm and in his own little world instead of yelling or hitting things.
It's very difficult for someone to willingly look at their flaws and try to make a change; even if they try, sometimes they aren't provided with the right inspirations and resources. I'm glad that Marijuana has kept him from anger and abuse, and that he atleast was temporarily held from expressing those emotions physically. I also agree that it's not your decision to change him, and that I know you know that he has to change willingly before any progress could be made. But I don't believe that it fixed the problem, it only put him on hold, and that's not dealing with the problem, it's just avoiding it. I don't really care, nor mind, that he uses Marijuana, I just know that it's not cracked up to what it's supposed to be.
I think it all drops down to moderation. If one is always high, then they lose knowledge of what it is like to function and create things and think while they are not high. I have seen this happen to many people. They're just constantly stoned and have no idea what's going on. They have made it a priority to get high all the time. But this is their own destructive choice. "Everything in moderation," the great philosophers always say.
Technically, everything changes your life. If I didn't respond to you and just Kameron, than you wouldn't be reading this, and you wouldn't know where I stand regarding your words. And when it falls down to it, if I carry your arguement with me and mention it, you becoming obliged to be more active in the discussion. And the discussion can certaintly affect you more than eating an orange!
I sort of agree with what you're saying; I'm glad you understand that Marijuana should be a mean of experimentation rather than casual habit. I don't have a problem with Marijuana as much as I do the pseudo-intellectual culture it breeds, and an incessant need to "legalize" or "decriminalize". Drugs aren't natural for the body. They can heal you, they can make you forget, they can make you pay attention, but they're foreign substances that alter your mind beyond the experience and they always will be. Whether they help you or hurt you, they're not necessary for you to live a happy life, and that notion is forgotten in the smoke of pot culture.
