To bamboozle consumers, some e-cigarettes are marketed as “hookah pens” or “e-hookahs” or “vape pipes.” The devices, a segment of the fast-growing e-cigarette market, are being shrewdly marketed to avoid the stigma associated with cigarettes of any kind. The products come in a rainbow of colors and candy-sweet flavors but, beneath the surface, they are often virtually identical to e-cigarettes, right down to their addictive nicotine and unregulated swirl of other chemicals. The emergence of e-hookahs and their ilk is frustrating public health officials already struggling to halt the spread of e-cigarettes, particularly among young people. Separately, the Los Angeles City Council voted to join New York and Chicago in banning e-cigarettes in parks, restaurants and most workplaces. The New York Times, Bloomberg, Los Angeles Times

Illinois attorney general accuses Koch brothers company of polluting river. KCBX Terminals, a company piling petroleum coke on Chicago’s Southeast Side that already was targeted as a source of lung-damaging air pollution, now faces claims that it illegally allowed contaminated runoff to spill into the Calumet River. In a lawsuit, the Illinois attorney general urged a judge to cite KCBX for violating water quality and open dumping laws by failing to prevent petroleum coke and coal from washing into the river. State environmental investigators found that the only thing separating the black mounds from the river were sandbags on a narrow walkway — and several sandbags were missing or out of place. KCBX, controlled by industrialists Charles and David Koch, also is defending a state suit accusing it of violating air pollution laws at another Chicago site. Chicago Tribune

U.S.  judge rules that a record $9.5 billion environmental-damage award against Chevron was tainted. In the latest twist in one of the longest-running legal battles in corporate history, the judge found that New York lawyer Steven Donziger and his litigation team engaged in coercion, bribery, money laundering and other misconduct to win a 2011 verdict against Chevron in Ecuador. The decision, which gives the oil giant a boost in its battle against a global effort to seize its assets, bars Donziger and his two Ecuadorean co-defendants from profiting from the award and excoriates the plaintiffs attorney, who has spent the bulk of his career pursuing the case. The judge concluded that Donziger and his team fabricated evidence, promised $500,000 to an Ecuadorean judge to rule in their favor and ghostwrote much of the final verdict.

Italy’s antitrust regulator fines Novartis and Roche Holding $251 million for alleged collusion. Authorities said the two Swiss-based companies tried to prevent the use of Roche’s Avastin cancer drug as a treatment for an eye disease in favor of a far more expensive drug, Lucentis, that the companies market jointly for an eye malady known as wet age-related macular degeneration. The companies said they have no agreement to restrict competition and they plan to appeal. Avastin is approved only for cancer, but both it and Lucentis belong to a family of medicines that prevent blood-vessel growth. For that reason, and because Lucentis costs more, some U.S. and European doctors use Avastin to treat the eye condition. Roche and Novartis represented Avastin as a “more dangerous” drug, the regulator said.

Cost and lack of awareness prevent civilian victims of violence from getting post-traumatic stress disorder treatment. Even though a national study of patients with traumatic injuries has found that more than 20 percent of them develop PTSD, many hospitals still have no systematic approach to helping people who need treatment. A survey of 21 top-level trauma centers in cities with high rates of violence found that only one, the Interim LSU Public Hospital in New Orleans, screens all acutely injured patients for PTSD. Along with the cost of treatment and a lack of awareness among patients and trauma surgeons about the extent of the problem, efforts to provide treatment are crimped by a shortage of mental health professionals.
