Step-by-step explanation:
MDMA, also known as ecstasy or Molly, is a psychoactive drug that is commonly found in tablet form with various colors and logos, particularly targeting younger demographics. MDMA is known to act as a euphoriant, empathogen, and to some extent possesses stimulant or hallucinogenic effects. Despite its pervasive use, as of 2016, MDMA had no accepted medical uses, though it was being tested for potential therapeutic applications, such as in the treatment of post-traumatic stress disorder (PTSD) and certain anxiety disorders. It should be noted that though MDMA is sometimes referred to for potential medical purposes, its majority usage is recreational, which can lead to adverse health effects including anxiety, hallucinations, paranoia, and changes in neurotransmitter levels with repeated use.
