Synthetic Marijuana
The United States Drug Enforcement Administration (DEA) recently used its emergency scheduling authority to temporarily control five chemicals (JWH-018, JWH-073, JWH-200, CP-47,497, and cannabicyclohexanol) used to make “fake pot” products, also known as synthetic marijuana.  They are now designated as Schedule I substances, the most restrictive category, which is reserved for unsafe, highly abused substances with no medical usage.
This action will make possessing and selling these chemicals or the products that contain them illegal in the U.S. for at least one year while the DEA and the United States Department of Health and Human Services (DHHS) further study whether these chemicals and products should be permanently controlled. 
Over the past year, these herbal blends have been marketed as providing a marijuana-like high and have become increasingly popular, particularly among teens and young adults.  These products consist of chemicals that mimic THC, the active ingredient in marijuana, and are sold at a variety of retail outlets, in head shops and over the Internet.  The products have been sold under various names such as “Spice,” “K2,” “Blaze,” and “Red X Dawn” and are labeled as herbal incense.

Synthetic Cocaine
Marketed as “bath salts” or “plant feeder,” the new product on the market is being used as a synthetic cocaine.  Like synthetic marijuana, these “bath salts” are available in retail shops, smoke shops, convenience stores, and on the Internet.  Sold under the names “Ivory Wave,” “White Lightening” and “Hurricane Charlie,” these are not the bath salts you pour in your tub to soak in after a long hard day at work.  These so-called bath salts are intended to be snorted, smoked or injected – and users are getting high off of them.
The Drug Enforcement Administration (DEA) has yet to regulate these products which are said to have similar effects of methamphetamine. The powders often contain mephedrone and methylenedioxypyrovalerone, also known as MDPV, and can cause hallucinations, paranoia, rapid heart rates and suicidal thoughts. MDPV and mephedrone are made in a lab, and they aren't regulated because they're not marketed for human consumption.
Recently, a man in Fulton, MS, high on bath salts, slit his face and stomach while under the influence of bath salts.  He survived but others have not been so lucky. Several incidents have been reported where users have slashed their throats or shot themselves while under the influence of the so-called bath salts.  These drugs, although they produce a horrible trip, cause an intense craving, causing users to binge on them over and over again.
