Drugs are all around us. Some of them are more harmful to our health and/or relationships than others.
From a scientific perspective, alcohol and tobacco are far more toxic and harmful than pot. In fact, one of the only cons to pot is that most people smoke it, which is bad for your lungs. If you eat it it reduces the health risks to near negligible.
Legal or Illegal is not a valid argument when discussing drugs. It is high time (hehe sorry) that people stopped treating drugs as a criminal problem, and started treating them as a health/social issue. Drugs have been with people since the earliest times. This is an archaeologically verified truth. The need for humans to temporarily alter thier state of conciousness can be observed even in small children who learn that spinning will make them dizzy (and they do it again and again, who here can say they didnt do that?)
Frankly, I think America has a terrible attitude toward drugs. Why criminalize a large portion of your population who are otherwise decent people? What people need is a proper education when it comes to drugs. And not just the "say no" propoganda you read/see every day. I'm speaking of facts. The three most widely consumed "legal" drugs (alcohol, tobacco, caffine) are also three of the most dangerous/toxic. Most people dont see this (especially with caffine and alcohol) because society condones them. This legality does not make them any better or safer!
I'm not pro or anti anything when it comes to drugs. I think people need to be made aware of the facts, the helath issues and social ramifications of using a drug. I think after that, we should just let people be people.
