The effects of medical marijuana laws on illegal marijuana use

Marijuana legalization and disability claiming

“…Chu uses administrative data and shows that MML passage leads to a 10% to 20% increase in arrests for marijuana-related possession and substance abuse treatment admissions (Chu, 2014(Chu, , 2015. Pacula et al (2015) show that passage of an MML leads to a 14% reduction in marijuana-related substance abuse treatment admissions using the same dataset as Chu (2014) and no change in self-reported marijuana use among a sample of young adults in the National Survey of Youth 1997.…”

“…Pacula et al (2015) show that passage of an MML leads to a 14% reduction in marijuana-related substance abuse treatment admissions using the same dataset as Chu (2014) and no change in self-reported marijuana use among a sample of young adults in the National Survey of Youth 1997. The authors note, however, that passage of an MML that allows for dispensaries increases both marijuana-related admissions to substance abuse treatment and self-reported marjuana use among young adults, while passage of an MML that requires patients to register with the state reduces such admissions and use.…”

Irish General Practitioner (GP) Perspectives Toward Decriminalisation, Legalisation and Cannabis for Therapeutic Purposes (CTP)

“…Some States in the US have shifted their policy stance to permit use of cannabis for therapeutic purposes (CTP) (Chu, 2014). This legalisation in the form of de facto supply for medical use has not caused increased consumption, prevalence of use or related adverse consequences (Nussbaum, Boyer & Kondrad, 2011;Hall & Weier, 2015;Sznitman and Zolotov, 2015;Ziemianski, Capler, Tekanoff , Lacasse, Luconi & Ware, 2015) and according to one study has contributed to heightened patient perceptions of safety and awareness (Trout & DiDonato, 2015).…”

High times: The effect of medical marijuana laws on student time use

“…Should such "effects" be observed, this is evidence of differential, pre-existing trends 6 One potential concern with the binary MML indicator is that there is potential heterogeneity across state legislations (e.g., whether or not the state allows dispensaries) . However, Chu (2015) and Wen, Hockenberry, and Cummings (2015) find little evidence that such differences are practically important. Moreover, it is difficult to distinguish differences in laws from regime/time effects, as most MMLs allowing for dispensaries were passed after 2008 and only a handful of states enacted any specific type of MML at a given time.…”

“…Several recent studies provide evidence of a causal relationship and show that MMLs cause a 10-20% increase in marijuana use (Chu 2014(Chu , 2015Wen, Hockenberry, and Cummings 2015). Somewhat surprisingly, the increase in marijuana use is concentrated among adults, as MMLs do not affect marijuana usage among juveniles (Wen, Hockenberry, and 3 Cummings 2015;Anderson, Hansen, and Rees 2015).…”
