Re: Does eating food effect the trip?
Most forms of LSD are absorbed in the mouth (i.e. blotter) not in the gut. Sublingual absorption is a very fast route into the system, and one reason that heart patients who take nitroglycerin and need it to act fast, place the nitro under the tongue. The conventional wisdom is that eating and tripping are fine. Stop starving SWIY.
OTOH, not everything can be absorbed sublingually. With substances that are taken orally and absorbed by the gut, the rationale behind taking medications and such on an empty stomach is to prevent the digestive process from starting - it allows the medication to pass through the stomach and duodenum quickly and be absorbed by the small intestines rather than by the stomach. Much faster than if the digestive process is in full swing with a tummy full of dinner.
