question: What is on bath salts packaging to avoid drug laws?
answer: "not for human consumption"
context: Title: Methylenedioxypyrovalerone
  Passage: Methylenedioxypyrovalerone (MDPV) is a stimulant of the cathinone class which acts as a norepinephrine-dopamine reuptake inhibitor (NDRI).  It was first developed in the 1960s by a team at Boehringer Ingelheim.  MDPV remained an obscure stimulant until around 2004 when it was reportedly sold as a designer drug.  Products labeled as bath salts containing MDPV were previously sold as recreational drugs in gas stations and convenience stores in the United States, similar to the marketing for Spice and K2 as incense.
  Title: Dibutylone
  Passage: Dibutylone (bk-DMBDB,) is a stimulant drug of the amphetamine, phenethylamine, and cathinone drug classes.  It is structurally related to butylone, a designer drug that has been detected in products marketed as bath salts or plant food.
  Title: Pamela's Law
  Passage: Pamela's Law is legislation that was passed in 2011 by the New Jersey Legislature and signed by Governor Chris Christie that bans the sale or possession of methylenedioxypyrovalerone (MDPV, most commonly found in the drug "bath salts").
  Title: Bath salts
  Passage: Bath salts are water-soluble, pulverised minerals that are added to water to be used for bathing.  They are said to improve cleaning, enhance the enjoyment of bathing, and serve as a vehicle for cosmetic agents.  Bath salts have been developed which mimic the properties of natural mineral baths or hot springs.  Some bath salts contain glycerine so the product will act as an emollient, humectant or lubricant.  Fragrances and colors are often added to bath salts; the fragrances are used to increase users' enjoyment of the bathing experience.
  Title: History of bipolar disorder
  Passage: Cyclical variations in moods and energy levels have been recorded at least as far back as several thousand years.  The words "melancholia" (an old word for depression) and "mania" have their etymologies in Ancient Greek.  The word melancholia is derived from "melas"/μελας, meaning "black", and "chole"/χολη, meaning "bile" or "gall", indicative of the term’s origins in pre-Hippocratic humoral theories.  A man known as Aretaeus of Cappadocia has the first records of analyzing the symptoms of depression and mania in the 1st century of Greece.  There is documentation that explains how bath salts were used to calm those with manic symptoms and also help those who are dealing with depression.  Even today, lithium is used as a treatment to bipolar disorder which is significant because lithium could have been an ingredient in the Greek bath salt.  Centuries passed and very little was studied or discovered.  It wasn't until the mid-19th century that a French psychiatrist by the name of Jean-Pierre Falret wrote an article describing "circular insanity" and this is believed to be the first recorded diagnosis of bipolar disorder.  Years later, in the early 1900s, Emil Kraepelin, a German psychiatrist, analyzed the influence of biology on mental disorders, including bipolar disorder.  His studies are still used as the basis of classification of mental disorders today.
  Title: Elaine Bartlett
  Passage: Elaine Bartlett was a woman charged with a first offense felony for selling cocaine.  Elaine, a mother of four children, spent sixteen years in the Bedford Hills prison in New York.  During the time of Elaine's arrest, New York had just undergone some major changes with their drug laws.  The controversial Rockefeller drug laws caused a major upset and cause many to second-guess the criminal justice system's benign motives.  After he release in 2000, Elaine had no proper resources to help her get back on track with her life but that was not an excuse for her.  Bartlett was a woman on a mission who was going to prove to not only to herself, but to the world that she was going to make it.  After having lived through sixteen years in prison, she became an activist to repeal the Rockefeller drug laws.  Bartlett helped found the Mothers of the Disappeared which is an advocacy group that is fighting to try and repeal the drug laws.  Not only has Bartlett helped found this organization, but she has also gone up against New York state legislators, and delivered speeches at rallies.  Besides the Rockefeller drug laws, Bartlett has also made an impact in attending anti-drug law events in Washington D.C., Philadelphia, and Texas.  While Elaine was still in prison, she wanted to be involved with as many activities as she possibly could in order to keep busy and to show that she had the full potential to better herself and get an education.  In 1999, Bartlett obtained her associate degree from Mercy College while she was still in prison.

  Title: Bath salts (drug)
  Passage: "Bath salts" (also called "psychoactive bath salts" or "PABS") is a term used in North America and Europe to describe a number of recreational designer drugs.  The name derives from instances in which the drugs were sold disguised as true bath salts.  The white powder, granules, or crystals often resemble true bath salts such as Epsom salts, but are very different chemically.  The drugs' packaging often states "not for human consumption" in an attempt to circumvent drug prohibition laws. Bath salts have also been similarly disguised as plant food, hookah cleaner, and other products.
  Title: 4'-Methyl-α-pyrrolidinopropiophenone
  Passage: 4'-Methyl-α-pyrrolidinopropiophenone (4-MePPP, MPPP or MαPPP) is a stimulant drug and substituted cathinone.  It is structurally very similar to α-PPP, with only one added methyl group in the para position on the phenyl ring.  4-MePPP was sold in Germany as a designer drug in the late 1990s and early 2000s, along with a number of other pyrrolidinophenone derivatives.  Although it has never achieved the same international popularity as its better-known relations α-PPP and MDPV, 4-MePPP is still sometimes found as an ingredient of grey-market "bath salt" blends such as "NRG-3".
