§ 830, concerning the sale of pseudoephedrine-containing products. The law mandated two phases, the first needing to be implemented by April 8, 2006, and the second to be completed by September 30, 2006. The first phase dealt primarily with implementing the new buying restrictions based on amount, while the second phase encompassed the requirements of storage, employee training, and record keeping. Though the law was mainly directed at pseudoephedrine products it also applies to all over-the-counter products containing ephedrine, pseudoephedrine, and phenylpropanolamine, their salts, optical isomers,
and salts of optical isomers. Pseudoephedrine was defined as a "scheduled listed chemical product" under 21 U.S.C. § 802(45(A)). The act included the following requirements for merchants ("regulated sellers") who sell such products:

Required a retrievable record of all purchases, identifying the name and address of each party, to be kept for two years
Required verification of proof of identity of all purchasers
Required protection and disclosure methods in the collection of personal information
Required reports to the Attorney General of any suspicious payments or disappearances of the regulated products
Required training of employees with regard to the requirements of the CMEA. Retailers must self-certify as to training and compliance.
Ion Ţiriac, the president of the Romanian Olympic Committee, resigned over the scandal.In the 2010 Winter Olympic Games, the IOC issued a reprimand against the Slovak ice hockey player Lubomir Visnovsky for usage of pseudoephedrine.In the 2014 Winter Olympic Games Team Sweden and Washington Capitals ice hockey player Nicklas Bäckström was prevented from playing in the final for usage of pseudoephedrine. Bäckström claimed he was using it as allergy medication. In March 2014, the IOC Disciplinary Commission decided that Bäckström would be awarded the silver medal. In January 2015 Bäckström, the IOC, WADA and the IIHF agreed to a settlement in which he accepted a reprimand but was cleared of attempting to enhance his performance. Detection of use
Pseudoephedrine may be quantified in blood, plasma, or urine to monitor any possible performance-enhancing use by athletes, confirm a diagnosis of poisoning, or to assist in a medicolegal death investigation. Many commercial immunoassay screening tests directed at the amphetamines cross-react appreciably with pseudoephedrine, but chromatographic techniques can easily distinguish pseudoephedrine from other phenethylamine derivatives. Blood or plasma pseudoephedrine concentrations are typically in the 50–300 µg/l range in persons taking the drug therapeutically, 500–3000 µg/l in people with substance use disorder involving pseudoephedrine, or poisoned patients and 10–70 mg/l in cases of acute fatal overdose. Chemistry
Pseudoephedrine is a diastereomer of ephedrine and is readily reduced into methamphetamine or oxidized into methcathinone. Nomenclatures
The dextrorotary (+)- or d- enantiomer is (1S,2S)-pseudoephedrine, whereas the levorotating (−)- or l- form is (1R,2R)-pseudoephedrine.
