No, it is a gateway drug because it emboldens the timorous to experiment further. Whether legal or not, the effects are the same. It creates a false escape rather than force one to have to deal with reality and become strengthened in resolve and character as a result. When a "high" is experienced, it only creates the desire to go further. There is no moral "wall" where the experimenter says, "No, that one is not good, so I will not try it."
