I don't think either of these people made smart choices. But the reason their judgment was clouded has everything to do with the frightening consequences of our drug laws. People are terrified of the drug war and sometimes make unfortunate decisions. Sure, they could refrain from using if they're afraid of jail, but that's no excuse for marijuana laws that hurt people worse than marijuana. Events like these are not the sign of a healthy society with a healthy drug policy.

If our laws cause suicides and police chases, they are quite clearly not making us safer.
