Extraction - A question about wild morning glory and another about potency in extraction.

[Madjnun]

So, SWIM is about to try extraction with morning glory seeds for the first time. He was planning on it before finding this site and then stumbled upon this and all his dreams came true. The cold water extraction method is well understood by this guy and he knows what he's doing, but has not done it before. So he has a couple of questions.

The first is about the issue of potency. This guy went through a phase where he experimented with several psychedelics and related drugs and has attempted to do morning glory seeds three times by eating them. The second attempt did nothing. The third resulted in puking and a fuzzy feeling but the first was entirely successful with just a little nausea. SWIM made both these attempts with 800-1200 seeds. Will the cold water extraction methods with about 800 seeds produce the same quality of effects as eating them did? If not, higher or lower?

SWIM is also to the point in his thinking on drugs where he wants to do everything as naturally as possible and has an assload of morning glory plants growing up the side of his house. Is this a safe way to get them? He and another friend(who is an expert on plants, not just drug related) both believe these plants to be at least very close to the Heavenly Blue seeds both have tried before. His experiences in the past came from Home Depot(successful), Lowes(puking), and local garden store(nothing).

Thank you for your help.
