Weed, also known as marijuana, is a drug made from the leaves and flowers of the hemp plant. It is commonly consumed by smoking or vaporizing the dried plant material and can cause feelings of relaxation, euphoria and altered sense of time.
Mushrooms, specifically "magic mushrooms", contain the psychoactive compound psilocybin, which when consumed, can cause hallucinations and changes in perception, mood and thought. They are typically consumed by eating dried or fresh mushrooms or by taking a psilocybin capsule.
MDMA, also known as Ecstasy or Molly, is a synthetic drug that produces feelings of euphoria, increased energy, and emotional warmth. It is often consumed in the form of a pill and its effects usually last for 3-6 hours. Long-term use can lead to cognitive impairment and damage to the brain serotonin system.
