Sunset is a drug that allows vampires to exist in the sun, created by Xelco Inc. The ingredients of the drug are unknown. There are no studies on the long term effects of the drug at this time. However, it appears to most that the drug can be habit forming and damaging to the bones. Also it is unclear if humans can smell the odor that emits from the drug, but it definitely has a pungent odor that vampires can smell. Therefore, it seems that a trade off is made with this as with most drugs. Careful thought needs to be put into the risks and benefits of the drug.
