LSD is not very we'll studied because it is so illegal. The U.S. government won't let anyone do research on it, which, is unfortunate because it is so highly active. LSD takes a very small dosage to induce effects on the body and mind when compared to aspirin. Asprin reduces blood vessel constriction, LSD..., the effect is not entirely undersood. The first order hallucinations LSD induces are much different than the second order delusions brought on by alcohol and intoxicants. LSD is a true hallucinogen one of the strongest discovered. LSD is not slowly poisoning the organism like intoxicants. LSD is acting on the brain in such a way that it will produce vivid hallucinations. Whether it makes your brain bleed I hope not cause then mine would be bloody.
