US CA: Edu: OPED: Legalizing Marijuana in California Would Be

The Daily Californian, 23 May 2016 - Lt. Gov. Gavin Newsom, a proponent of the legalization effort, should be reminded that his most important responsibility as an elected official is to protect the people from all enemies, foreign and domestic. The Adult Use of Marijuana Act is rumored to be bankrolled by billionaires who do not have California's best interest in mind. New York billionaire Sean Parker has purportedly been recruited to augment money that will flow from George Soros and the Drug Policy Alliance. They didn't earn billions because they are dumb, but apparently they think we are. Their stated benefits of legalization are frankly an affront to one's intellect. It is a lie to say this will protect children. Proponents of this act want to tax and regulate marijuana and teach our kids not to use it. Absurd! Expanding the availability and access will increase adolescent use as it has in Colorado and Washington. Ability for anyone to grow 6 plants in a home will endanger children living there and provide even easier access for kids and their friends, while serving as a magnet for home invasion robberies.

Canada: Tobacco, Marijuana Are Exactly the Same When It Comes

Globe and Mail, 23 May 2016 - Is eating a pot brownie each day to help with your chronic pain as bad for you as regularly lighting up a cigarette? Canadian life insurers say the two activities pose the same risk and demand the same higher premiums from clients. The insurance industry's national trade association argues the standard policy among insurers of tacking on increased costs to marijuana users - regardless of whether they smoke, vape or eat the drug - is based on available research. The group also suggests pricier premiums could be due to the severity of a medical marijuana patient's underlying conditions.

US MD: Advocates Frustrated As Medical Marijuana Inches

Richmond Times-Dispatch, 23 May 2016 - Maryland's state medical marijuana commission delivered a blow to marijuana advocates and would-be entrepreneurs last week by abruptly capping the number of businesses that can process marijuana into pills, oils and other products. The commission also gave conflicting information about when the first long-awaited growing licenses would be issued, with Executive Director Patrick Jameson first saying it would be late summer or early fall, then stating that licenses would come "weeks" after the evaluations of the applications are completed in early July.

US FL: Backers: State Pot Industry Worth Billions

US PA: New Law May Help In Fight Against Opioid Crisis

The Daily Local, 23 May 2016 - NEW LAW MAY HELP IN FIGHT AGAINST OPIOID CRISIS Can the legalization of one drug help decrease abuse of another drug?

  1. Since 1996, ten states have legalized medical marijuana use: AK, AZ, CA, CO, HI, ME, NV, OR, VT and WA. Eight of the ten did so through the initiative process, Hawaii's law was enacted by the legislature and signed by the governor in 2000, and Vermont's was enacted by the legislature and passed into law without the governor's signature in May 2004.

  2. The Institute of Medicine's 1999 report on medical marijuana stated, "The accumulated data indicate a potential therapeutic value for cannabinoid drugs, particularly for symptoms such as pain relief, control of nausea and vomiting, and appetite stimulation."

  3. The Institute of Medicine's 1999 report on medical marijuana examined the question whether the medical use of marijuana would lead to an increase of marijuana use in the general population and concluded that, "At this point there are no convincing data to support this concern. The existing data are consistent with the idea that this would not be a problem if the medical use of marijuana were as closely regulated as other medications with abuse potential." The report also noted that, "this question is beyond the issues normally considered for medical uses of drugs, and should not be a factor in evaluating the therapeutic potential of marijuana or cannabinoids."

  4. In the Institute of Medicine's report on medical marijuana, the researchers examined the physiological risks of using marijuana and cautioned, "Marijuana is not a completely benign substance. It is a powerful drug with a variety of effects. However, except for the harms associated with smoking, the adverse effects of marijuana use are within the range of effects tolerated for other medications."

  5. The Institute of Medicine's 1999 report on medical marijuana examined the question of whether marijuana could diminish patients' immune system - an important question when considering marijuana use by AIDS and cancer patients. The report concluded that, "the short-term immunosuppressive effects are not well established but, if they exist, are not likely great enough to preclude a legitimate medical use."

  6. "Conclusions: Smoked and oral cannabinoids did not seem to be unsafe in people with HIV infection with respect to HIV RNA levels, CD4+ and CD8+ cell counts, or protease inhibitor levels over a 21-day treatment."

    Source:  Abrams, Donald I., MD, et al., "Short-Term Effects of Cannabinoids in Patients with HIV-1 Infection - A Randomized, Placebo-Controlled Clinical Trial," Annals of Internal Medicine, Aug. 19, 2003, Vol. 139, No. 4 (American College of Physicians), p. 258.

  7. "This study provides evidence that short-term use of cannabinoids, either oral or smoked, does not substantially elevate viral load in individuals with HIV infection who are receiving stable antiretroviral regimens containing nelfinavir or indinavir. Upper confidence bounds for all estimated effects of cannabinoids on HIV RNA level from all analyses were no greater than an increase of 0.23 log10 copies/mL compared with placebo. Because this study was randomized and analyses were controlled for all known potential confounders, it is very unlikely that chance imbalance on any known or unknown covariate masked a harmful effect of cannabinoids. Study participants in all groups may have been expected to benefit from the equivalent of directly observed antiretroviral therapy, as well as decreased stress and, for some, improved nutrition over the 25-day inpatient stay."

  8. "Nevertheless, when considering all 15 studies (i.e., those that met both strict and more relaxed criteria) we only noted that regular cannabis users performed worse on memory tests, but that the magnitude of the effect was very small. The small magnitude of effect sizes from observations of chronic users of cannabis suggests that cannabis compounds, if found to have therapeutic value, should have a good margin of safety from a neurocognitive standpoint under the more limited conditions of exposure that would likely obtain in a medical setting."

  11. A few of the editorial boards that have endorsed medical access to marijuana include: Boston Globe; Chicago Tribune; Miami Herald; New York Times; Orange County Register; and USA Today.

  12. Many organizations have favorable positions (e.g., unimpeded research) on medical marijuana. These groups include: The Institute of Medicine, The American Cancer Society; American Medical Association; Australian Commonwealth Department of Human Services and Health; California Medical Association; Federation of American Scientists; Florida Medical Association; and the National Academy of Sciences.

  13. The Controlled Substances Act of 1970 established five categories, or "schedules," into which all illicit and prescription drugs were placed. Marijuana was placed in Schedule I, which defines the substance as having a high potential for abuse, no currently accepted medical use in the United States, and a lack of accepted safety for use under medical supervision. To contrast, over 90 published reports and studies have shown marijuana has medical efficacy.

  15. On September 6, 1988, the Drug Enforcement Administration's Chief Administrative Law Judge, Francis L. Young, ruled:
    "Marijuana, in its natural form, is one of the safest therapeutically active substances known....[T]he provisions of the [Controlled Substances] Act permit and require the transfer of marijuana from Schedule I to Schedule II. It would be unreasonable, arbitrary and capricious for the DEA to continue to stand between those sufferers and the benefits of this substance."

    Source: US Department of Justice, Drug Enforcement Agency, "In the Matter of Marijuana Rescheduling Petition," [Docket #86-22] (September 6, 1988), p. 57.

  16. The DEA's Administrative Law Judge, Francis Young concluded: "In strict medical terms marijuana is far safer than many foods we commonly consume. For example, eating 10 raw potatoes can result in a toxic response. By comparison, it is physically impossible to eat enough marijuana to induce death. Marijuana in its natural form is one of the safest therapeutically active substances known to man. By any measure of rational analysis marijuana can be safely used within the supervised routine of medical care."
