Does moon opposition neptune indicate substance abuse?

my moon is in cancer, and my neptune in capricorn

I discovered that with a Moon/Neptune opposition, it usually brings confusion and deception. You may feel deceived or you may deceive others. This could come in the form of psychic readings, friends, or lovers.

neptune is the planet of escapism among many things of course. The opposition is considered a "negative" aspect by many, but I believe that it is neither negative or positive. The only really negative aspect is the square. The opposition represents awareness. Think about it: an opposition shows one planet at one end of the line, the other planet at the other end. The energies of one planet manifest on one side, while the other planets energies are manifested on the other. The thing with is an opposition is that there are the polarity cases. Everything has polarity: light and dark, good and evil, love and hate, etc. So, neptune is over in one corner generating mysticism, imagination, creativity, escapism, and illusion. The moon is in the other generating emotions, intuition, inner desires, personal traits, and nurture. So, although escapism isn't necessarily a strong indication, there may exist a tendency. But this aspect mainly means that you have natural and strong psychic abilities, and you are emotionally confused much of the time. You tend to project this confusion onto others, making them feel like they are unsure of their feelings. This can cause relationship tension. Your beliefs are vital to your emotional well-being.

Hope this helps!
