LSD
LSD is an artificially created chemical compound. A hallucionogen ususally swallowed taking effect within 30 minutes. Effects last for up to 12 hours of distortions in perception of the world, visual hallucinations, intense self-awareness, euphoria and deep spiritual-like sensations. Side effects can be a 'bad trip', which is an inescapable nightmare from the drugs effects and long term mental health problems.
