How many farmer-want-to-bes want to see me unload my load via autofellatio?

Haha now I'm not mining again.  If I didn't know better I'd swear that whoever is perpetrating this is reading the forum and seeing my tips.

I'll shut up now.

Well, I do. I don't think you do though. LD50 measures the median lethal dose of any substance. It doesn't have to be a drug. Even water has an LD50.

As for the rest of your post, the LD50 of a given drug is only a small part of the danger of mind altering substances. A larger concern is how such substances create permanent or at least long lasting changes to the brain.

That said, I support at least the decriminalisation of illicit drugs and education about their effects. Sending a person to prison for being an addict increases costs to society and provides a temporary benefit only if the addict committed crimes to pay for their addiction.

In the long run prohibition causes no decrease in drug use, a fantastic opportunity for organised crime to profit, and large costs to the state.
