Your gf is smart. I have no idea what would be safe to smoke, I do know there are clove cigarettes, kretek. Clove is pretty well rounded, great for banishing, protection, raise general vibrations. What do you mean with smoking absinthe? You mean wormwood?
I am not sure about the second and last ones but the rest are safe to smoke. If you mean absinthe the drink, it will add flavor but not much else. Lightly mist your herbs with it and let it dry a bit if you insist on it though.
I would recommend a blend of tobacco, mullein and catnip personally. The two other herbs are safe to smoke. Mullein is good for both cleansing and evocation while catnip has a calming effect that will counteract the edgy effects of the nicotine and relax the body to allow your astral senses to become more open.
Sure. Mullein has been used either by being carried or smoked by multiple cultures. The leaves have actually been used as part of Ceremony of certain Native American tribes such as the Navajo and Hopi (mainly to be brought back to center or to remove maddness). It would actually be added the pipes along with other herbs to help initiate the shamanic travel while still keeping the individual grounded. The Greeks would be carried the herb to protect themselves from magic. In England it was mixed with salt and dill to be sprinkled on properties to repel baneful sprints. As far as more modern practices, it is used as a substitute for graveyard dirt to help attract spirits of the dead. It is also is used as a tea to help ailments of the lungs, especially the flowers.
Catnip has connections with Native American tribes as well, such as the Cherokee, mainly for its medicinal properties. It is known for relaxing the body but was also viewed as a tonic for strength when made into a tea. As far as magic goes, it is often associated with luck, courage and love. I would recommend only a small pinch or so as it can give you a headache if you use too much. I actually used it to help with moving on from smoking marijuana when I had to get clean for a new job but was on edge.
Edit: I would recommend smoking this either just before or during the evocation or meditation
@Nicolas_Tomas its extremely healthy, idk about smoking it but its packed with amino acids and nutrients. You dont want to burn it, or you’ll destroy those properties. Hemp oil and hemp seeds are good for putting on salads. One of the healthiest foods on the planet. Its good for your body, your temple, therefore i believe it would be a positive incorporation to your magickal workings.
