MDMA aka Ecstay or Molly is a synthetic drug that alters mood and perception. It is chemically similar to stimulants and hallucinogens.
MDMA acts by increasing the activity of: dopamine, norepinephrine, and serotonin.
Sought after effects include euphoria, increased energy.
Some researchers suggest that sativas contain more uplifting, euphoric cannabinoids and terpenes than indicas, and high-CBD strains are shown to keep energy high as well.
