How has marijuana affected your meditations?

I have not ever used matijuana. The question assumes that one has. It would be better if it were phrased "If you use or have used marijuana does it affect your meditation? If so, how?

I don’t use it, so it hasn’t. I can meditate on my own without needing help from substances. Clean and crisp air is better to meditate in anyway. If you have to use substances in order to relax, then you need to get in touch with yourself and focus on relaxing and clearing your mind without aid from substance.
