Patients enrolled in the study at the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed) demonstrated improvement of mood and reduction of anxiety up to six months after undergoing treatment, with significance reached at the six-month point on the “Beck Depression
Inventory” and at one and three months on the “State-Trait Anxiety Inventory.” A third screening tool, the “Profile of Mood States,” identified mood improvement after treatment that approached but did not reach significance.

“We are working with a patient population that often does not respond well to conventional treatments,” said Charles S. Grob, MD, an LA BioMed principal investigator who led the research team. “Following their treatments with psilocybin, the patients and their families reported benefit from the use of this hallucinogen in reducing their anxiety. This study shows psilocybin can be administered safely, and that further investigation of hallucinogens should be pursued to determine their potential benefits.”

Researchers conducted extensive investigations of psychedelic drugs in the 1950s and 1960s and found promising improvements in mood and anxiety, as well as a diminished need for narcotic pain medication among advanced-stage cancer patients. The research was abandoned in the early 1970s in the wake of widespread recreational usage that led to stiff federal laws regulating hallucinogens.

“Political and cultural pressures forced an end to these studies in the 1970s,” said Dr. Grob. “We were able to revive this research under strict federal supervision and demonstrate that this is a field of study with great promise for alleviating anxiety and other psychiatric symptoms.”

The LA BioMed study is the first research publication in several decades to examine the hallucinogen treatment model with advanced-cancer anxiety. Twelve volunteers, ages 36 to 58, with advanced-stage cancer and anxiety were given a moderate dose of 0.2 mg/kg of psilocybin and, on a separate occasion, a placebo. Neither the volunteers nor the researchers monitoring them knew whether they’d been given a placebo or psilocybin.

The two experimental sessions took place several weeks apart in a hospital clinical research unit at Harbor-UCLA Medical Center, where Dr. Grob is a professor of psychiatry. The research volunteers were monitored for the six hours following their dose. The volunteers were encouraged to lie in bed, wear eye shades and listen to music during the first few hours after ingesting the medication or the placebo. They were interviewed after the six-hour session and over the next six months to assess the outcome of the treatment.

Physorg.com: Whether teenagers who smoked pot will use other illicit drugs as young adults has more to do with life factors such as employment status and stress, according to the new research. In fact, the strongest predictor of whether someone will use other illicit drugs is their race/ethnicity, not whether they ever used marijuana.

Conducted by UNH associate professors of sociology Karen Van Gundy and Cesar Rebellon, the research appears in the September 2010, issue of the Journal of Health and Social Behavior in the article, “A Life-course Perspective on the ‘Gateway Hypothesis.’ ”

“In light of these findings, we urge U.S. drug control policymakers to consider stress and life-course approaches in their pursuit of solutions to the ‘drug problem,’ ” Van Gundy and Rebellon say.

The researchers used survey data from 1,286 young adults who attended Miami-Dade public schools in the 1990s. Within the final sample, 26 percent of the respondents are African American, 44 percent are Hispanic, and 30 percent are non-Hispanic white.

The researchers found that young adults who did not graduate from high school or attend college were more likely to have used marijuana as teenagers and other illicit substances in young adulthood. In addition, those who used marijuana as teenagers and were unemployed following high school were more likely to use other illicit drugs.

However, the association between teenage marijuana use and other illicit drug abuse by young adults fades once stresses, such as unemployment, diminish.
