In 2001, after completing the second season of The West Wing, Sorkin had a drug relapse, and was arrested at Hollywood Burbank Airport for possession of hallucinogenic mushrooms, marijuana, and crack cocaine. He was ordered by a court to attend a drug diversion program. There was huge media interest but he did make a successful recovery. In 2002, Sorkin criticized NBC News anchor Tom Brokaw's television special about a day in the life of a president, "The Bush White House: Inside the Real West Wing", comparing it to the act of sending a valentine to President George W. Bush instead of real news reporting. The West Wing aired on the same network, and so at the request of NBC's Entertainment President Jeff Zucker, Sorkin apologized, but later said, "there should be a difference between what NBC News does and what The West Wing TV series does."
In 1987, Sorkin started using marijuana and cocaine. He said cocaine gave him relief from certain nervous tensions that occur on a regular basis. In 1995, he sought rehabilitation at the Hazelden Institute in Minnesota, on the advice of Bingham to combat his addiction. In early 2001, Sorkin and his colleagues John Spencer and Martin Sheen received the Phoenix Rising Award for overcoming their drug abuse. However, on April 15, 2001, Sorkin was arrested when security guards at Hollywood Burbank Airport found that he was in possession of hallucinogenic mushrooms, marijuana, crack cocaine, and a metal crack pipe. He was court-ordered to a drug diversion program, while still working on The West Wing. In a commencement speech for Syracuse University on May 13, 2012, Sorkin said he has not used cocaine for eleven years.
A number of drugs, from crack cocaine to prescription opioids, have street names. Using these code words allows individuals, including teens, to hide drug use from parents, teachers and police officers.
The euphoric effects produced by methamphetamine, cocaine, and various designer amphetamines are similar and may be difficult to clinically differentiate.  A distinguishing clinical feature is the longer pharmacokinetic and pharmacodynamic half-life of methamphetamine, which may be as much as 10 times longer than that of cocaine. Because of the variability in quality and concentration of illicitly purchased methamphetamines, the clinical observation of toxic effects is more relevant than estimated total ingested dose. 
Abstract:This study discusses the oxidation induration and swelling behavior of chromium-bearing vanadium titanomagnetite pellets (CVTP) with Co2O3 additions. The reduction swelling index (RSI) and compressive strength of reduced CVTP (CSRC) were investigated with simulated coke oven gas (COG). The results show that the compressive strength (CS) of CVTP decreases from 2448 to 1983 N and the porosity of CVTP increases from 14.86 to 22.49% with increasing Co2O3 additions. The Co2O3 mainly exists in the form of CoFe2O4 in both of CVTP and reduced CVTP, and the CoFe2O4 is hard to be reduced by thermodynamic calculation. The Co-bearing phase mainly distributes on gap edges and among adjacent hematite grains. Many cracks and pores distribute along the grain boundaries and damage the connection of hematite grains. The CSRC decreases from 901 to 376 N, and RSI of reduced CVTP increases from 5.87 to 9.05% with increasing Co2O3 additions. The Co2O3 addition facilitates the aggregation and diffusion of metallic iron particles, and the aggregations of metallic iron thicken the lamellar crystals. The pores and interval of grains enlarge with increasing Co2O3 additions. This study can supply the theoretical and technical basis for the utilization of CVTP and waste residue-bearing cobalt with COG recyclable technology.Keywords: Co2O3; oxidation induration; reduction swelling index; coke oven gas; chromium-bearing vanadium titanomagnetite pellets 2b1af7f3a8
