Iranian Crystal: A misunderstanding of the crystal-meth

Abstract

• Sir,
  In Asia, Illicit opium and cannabis are produced mainly in Afghanistan, which makes major social and health problems for some countries, particularly Iran as the neighborhood^.[1]  In Iran, opium and hashish have been used for near 300 years,^[2] but other drugs such as heroin, buprenorphine, cocaine, tramadol, and ecstasy are new drugs of abuse in this country.
  ^[3-6] Abuses of the new drugs in Iran are now a major health problem, particularly for the youth and young adults^.[3,4]In Iran, drugs which have been named by substance abusers may have a similar western name, but with different chemical entity. For example, crack is one of the popular names among the substance abuser in Iran, but is totally different with the western crack. In the other parts of the world, the main ingredient of Crack is cocaine, but in Iran it is heroin which may also contain morphine, codeine, caffeine, noscapine, papaverine, dextromethorphan, and acetyl codeine or corticosteroids with different amounts that make it even more harmful than pure heroin or any other drugs^.[7]
  "Crystal meth," is the smokable form of methamphetamine hydrochloride. Crystal meth is more likely to cause dependence than other forms of methamphetamine. Crystal meth is a cheap and easily available drug in the western countries, which is a common abused drug among youths in these countries^.[8]
