Yes, the LP is in favor of the decriminalization of drugs.

For one thing, we don't particularly cotton to the government telling us what to do or not to do with our bodies. We believe in individual liberty, and that includes the freedom to ingest or not ingest chemicals. We believe people are free to smoke cigarettes, drink alcohol, eat fried chicken, or smoke a joint.

The same government that can outlaw marijuana is the same government that can ban alcohol (done that), ban cigarette smoking (on its way to doing that), or ban fried, unhealthy foods (haven't quite gotten this far yet).

The LP position is simple: small government, individual liberty. The criminalization of drugs is incompatible with both positions.

As far as abortion goes, the LP does have a position. For your convenience, I'll copy the relevant portion of the platform here:

Recognizing that abortion is a very sensitive issue and that people, including libertarians, can hold good-faith views on both sides, we believe the government should be kept out of the question.

We condemn state-funded and state-mandated abortions. It is particularly harsh to force someone who believes that abortion is murder to pay for another's abortion.

It is the right and obligation of the pregnant woman, not the state, to decide the desirability or appropriateness of prenatal testing, Caesarean births, fetal surgery, voluntary surrogacy arrangements, and/or home births.

IOW, the same stance the demos have with abortion, that it should be legal. I surmise partial birth abortion is covered under "fetal surgery".
