Different drugs, different effects, more harm... those are worth banning. Still, pot use is more widespread than any of these, and its the marijuana busts that pay for the SWAT team equipment for your local Barney Fife squad.
I hope none of those guys come around and shoot my dog, or yours for that matter.
You are not a libertarian, you are a socialist. Don't tell me that legalization is libertarian until we have a government that won't punish nonusers for the actions of users.
Why do you think Soros is funding legalization? He said it's the backdoor gateway to total socialism.
