You hear about drunk drivers killing people, not about high drivers killing people.
Probably because people generally get high somewhere safe, where they cannot be found, and, usually, cannot harm themselves or others there, places like their homes, for example.
Obviously, no one is ever going to stand for the banning of beer. Why not let people use a more minor 'drug' especially since it really isn't hurting anyone. And if it IS hurting themselves is it not their right to do it?
I don't stand for banning it, but restricting it is a good idea. Now, not many people will stand for this because it is easier to get high than drunk, meaning it will take a few beers to get you drunk, but a few minutes with weed could get you high, sometimes giving hallucinations, I've heard.
Can I no longer eat McDonalds because of how greasy it is?
Should I not use my computer as it hurts my eyes?
Maybe its 'unhealthy' but I still enjoy those things. Why not let people enjoy weed?
Faulty comparison alert! Yes, McDonalds is unhealthy, but it is open to... pretty much the entire world (With the exceptions of poor countries and some others), and marijuana isn't just "unhealthy," it
can prove dangerous.
However, McDonalds could be dangerous as well, and should be enjoyed in moderation, just like tobacco and alcohol, which is up to the consumers, and the same may apply to marijuana, being less dangerous than hardcore drugs, such as cocaine and LSD.
Conclusion: While I see no real reason that marijuana should be banned, I will say that I agree with the ban simply because I have no good reason to say that there shouldn't be.
