Following the dicussion with Mindexpansion, JDanger, Vertemorphous etc, here is the start of my collection of relevant research. This will be transferred to a thread shortly, and (if I had my way), would be avalable through the eventual (possible) website set up to provide advocacy and information to defend ethnobotanical cultivation and practices. Note that due to my university web access most of these links won't work, so you may have to use the citation provided and find a copy yourself. Enjoy!

"Development of a rational scale to assess the harm of drugs of potential misuse"

Summary(Abstract)

Drug misuse and abuse are major health problems. Harmful drugs are regulated according to classification systems that purport to relate to the harms and risks of each drug. However, the methodology and processes underlying classification systems are generally neither specified nor transparent, which reduces confidence in their accuracy and undermines health education messages. We developed and explored the feasibility of the use of a nine-category matrix of harm, with an expert delphic procedure, to assess the harms of a range of illicit drugs in an evidence-based fashion. We also included five legal drugs of misuse (alcohol, khat, solvents, alkyl nitrites, and tobacco) and one that has since been classified (ketamine) for reference. The process proved practicable, and yielded roughly similar scores and rankings of drug harm when used by two separate groups of experts. The ranking of drugs produced by our assessment of harm differed from those used by current regulatory systems. Our methodology offers a systematic framework and process that could be used by national and international regulatory bodies to assess the harm of current and future drugs of abuse.

Abstract

Research into treating drug dependence with hallucinogens, although promising, ended with questions still unanswered because of varying, in some cases skeptical, methodology and insufficient adherence to a double-blind, placebo-controlled design. Interest is again emerging, especially with the recent patenting in the United States of ibogaine for its apparent anti-craving properties. A review of the literature shows that these properties may be present across the entire family of hallucinogens. Potential efficacy may be tied to their agonism and antagonism at specific serotonin receptor sites. After the administration of a hallucinogen, there is a positive “afterglow” lasting weeks to months which might be extended through repeated dosing. Ibogaine and LSD both have lengthy periods of action, making their application unwieldy. However, tryptamines, such as N,N-Dimethyltryptamine (DMT), are so short-acting that they could easily be administered in an office setting. With numerous hallucinogens yet to be tested, a hallucinogen might well be discovered with superior anti-craving properties and non-deleterious side-effect profile.

From harm reduction to human rights: bringing liberalism back into drug reform debates"

"Andrew Hathaway notes that harm reduction seldom articulates or acknowledges the moral foundation on which it might build to affect meaningful changes in policy. He argues that despite the rhetorical strengths of empiricism, an openly liberal, human rights orientation imbues rational argument with the principles needed to sustain pragmatic drug reform solutions. Liberalism, with its norms of social tolerance and respect for civil liberties, is presented here as key to the future development of harm reduction discourse as a way of advancing human rights themes in contemporary drug policy debates."
