Why is pot or weed, looked down upon? What is "So" bad about it?

I'm not promoting the use marijuana because smoking anything is obviously bad for your health. However, if you couldn't already tell by my name, I happen to enjoy it thoroughly. The real "gateway drugs" are nicotine and alchohol. These two drugs are much more addictive and destructive and yet they are legal. Whether or not marijuana is legalized doesn't matter to me because I make my decisions based on morals, not laws. Illegal does not equate with immoral. The fact of the matter is that if marijuana was legalized it could potentially put the paper, textile, and plastic industies out of business. Not only that, it's a possible source of energy considering the fact that one of Henry Ford's first model of cars was made predominantly from hemp and was fueled by hemp oil. Not to mention the medicinal properties of marijuana. One man who used his money, power and influence back in the 20s or 30s convinced congress to make marijuana illegal. Followed by an onslaught of propaganda demonizing the so-called drug and its users. This man was William Randolph Hearst who was in the newspaper business and feared losing millions because he owned millions of dollars worth of timber yards for his papers. Think about it, if you can make paper out of hemp instead of trees which would be more efficient. I'd have to say hemp since it can grow virtually anywhere and is full grown after a matter of months as opposed to a lifetime. Henceforth, the nation was brainwashed into thinking that marijuana was the devil's weed and it remains to this day. As for marijuana being addictive I truly believe that it is not. I've been smoking for about 12 years and if I go a day or two without I'm just fine. No withdrawal symptoms, no agitation, nothing. However, I have a friend and I tell him he's the reason why people say marijuana is addictive because he thinks he needs it. What it boils down to is being weak minded. Nicotine and alchohol are legal because they cause more damage to the body, which in turn, is more money for the drug companies to collect as the sick try to get well, which in turn, the government collects more money from the drug companies because our government is owned by big business (drug, oil, tobacco, etc.) and of course the Federal Reserve. Ok, my rant has come to an end, it's all quite ridiculous if you ask me, but that's what it is.
