Legalizing weed would eventually put the United States to legalize all drugs.

Think about it,

In amounts above the legal limit, weed can, and will, get you high. When high people's reaction time slows down, and more accidents are bound to happen.

However, even if you want to argue that point, you can't argue the other one. If weed is legalized what will stop drug making/selling companies from around the world to come over to the United States and file a lawsuit to legalize their drug? If one drug is legalized, all drugs will be legalized. If all drugs are legalized people will get addicted, and drugs will take over the country. Just for a second consider what your children and grandchildren will have to go through if all of those drugs are legalized. When people are high people do crazy things. It's not going to be "cool" when your daughter is crossing the street and a guy high on weed has poor reaction time and kills her.

Think about the consequences before you make selfish comments.
