Yeah, lets start fresh.
My response was to an allegation of political machinations against minorities (and I think something about the cotton business and hemp). So I started out with the challenge that if that were so, would you expect to see prohibition worldwide -- and I think not.
However, my point doesn't mean there has to be the same rationale in every country, although I think the simplest explanation is that marijuana really is harmful (or is perceived to be harmful) pretty much across the board.
I'll also grant that the situation is different in different countries. Much like alcohol (which has demonstrable harm) a cultural tradition that includes marijuana use (such as in Mexico) will produce less harsher penalties. But I could find no country where marijuana use, sale and production was legal.
I think mostly it's illegal but sometimes the illegality is not enforced. So mostly we seem to be talking about decriminalization policies.
For instance, in India it is definitely, technically, illegal everywhere but traditions of use exist in certain states and during certain festivals and it is openly available in those contexts (it might even be regulated).
Checking Wikipedia it seems I'm mostly right:
Used during observance of certain Hindu rituals. Government-owned shops in holy cities like Varanasi sell cannabis in the form of bhang. Despite the high prevalent usage, the law makes it illegal to possess any form of the psychoactive. However, this law is rarely enforced and treated as a low priority across India. Further, large tracts of cannabis grow unchecked in the wild in many parts of northern and southern India in many states such as West Bengal, Tripura, Andhra Pradesh, Karnataka, Kerala, and Tamilnadu.[44] Many states such as West Bengal, Tripura, and the North East have their own laws allowing cannabis, locally known as ganja.
So maybe, unlike what I thought, it's even legal in some Indian states.
Since I am at it, let's check out the other oddballs by looking at the word legal. Do note that Wikipedia does not seem to be comprehensive on this (I don't see Thailand --which, IIRC, has the death penalty for cannabis traffickers). Also note that a lot of the information might be quite out of date:
Argentina:
Legal for personal use in small amounts and for consumption in private locations. Public consumption is generally accepted among young adults. Consumption for medical purposes is accepted but not legislated (only in private locations). Cultivating, selling and transporting large amounts is illegal and punishable by present laws.[
With the caveat that Wikipedia is marking the source as unreliable (it's in a website with the domain name "webehigh.com"), Iran is somewhat curious:
Growing cannabis is legal if planted for food purposes as the seeds are eaten by the Iranian people, and companies often draw oil from the seeds which is sold legally. A person is allowed to carry up to 15g of cannabis legally; for every gram above they will be charged 10000 Rials
Pakistan:
Laws prohibiting the sale and misuse of cannabis exist, but are very rarely enforced. As with hash, the occasional use of cannabis in community gatherings is broadly tolerated as a centuries old custom, despite its association with lower-income groups. The open use of cannabis by Sufis and Hindus as a means to induce euphoria has never been challenged by the state. Further, large tracts of cannabis grow unchecked in the wild.
Peru:
Possession of up to eight grams (0.28 oz) of marijuana is legal as long as one is not in possession of another drug.
Sweden:
Further information:
Legality of cannabis#Sweden and
Drug policy of Sweden
It is illegal to sell, transfer, purchase, use or possess any quantity of cannabis. Fines are the most common sanction in matters regarding personal use.
Switzerland:
Main article:
Cannabis in Switzerland
Cannabis is illegal to possess, consume or distribute. However, usually only the minimum penalty is imposed for possession and personal use, even for larger amounts. The federal council has committed to implement changes as to decriminalization of personal use and possession already in 2001, and the parliament is currently tasked to tender concrete approaches. As nothing is coming forth on a parliamentary basis, a referendum was launched in 2008, however abolished by the voters.
As of January 1, 2012, the cantons Vaud, Neuchatel, Geneva and Fribourg have allowed the growing and cultivation of up to 4 cannabis plants per person, in an attempt to curb illegal street trafficking.
I'll skip the United States since it's not what I was wondering about.
Uruguay:
Possession for personal use not penalized; law does not specify quantity for "personal" amount.
Looking for the word decriminalized ends up with oddballs actually being rather common. So I guess I'll stop here by mentioning the countries with decriminalization in some aspect of cannabis regulation rather than actually quoting Wikipedia: Australia, Belgium, Colombia, Costa Rica, Croatia, Cyprus, Czech Republic, Ecuador, Estonia, Finland, Israel, Mexico, Netherlands, Poland, Portugal and Spain.
Note that decriminalization seems to mean vastly different things in different places. Note that I am also missing some countries which have
de facto in which the Wikipedia editor didn't happen to use the word "decriminalization" (Jamaica comes to mind).
A curious case is Indonesia and I can see there that the information is obsolete. There, as of fairly recently, cannabis is legal for culinary use. As I cannot imagine this being compatible with "Personal use in small amounts: Maximum sentence of four years in prison (additional fines may apply) if caught by the police in possession, intoxication or by positive urine test." so I have to assume that those laws must have been amended (unless there's some sort of schizophrenic legal situation where they are
de facto decriminalized and not enforced).
What I was interested in was another explanation, other than my guess about perceived harm, that would explain the popularity of marijuana prohibition in so many disparate countries. For example, if the UN came out with a policy (driven by US wants) and other countries signed up just to go with the flow, that would be a good explanation and it would contradict my hypothesis.
Yes, that is exactly what I contend. The US does have a lot of influence. Other countries often follow the US lead. The UN often follows the US lead. Other countries often follow the UN lead.
Thinking about it, the signature of laws being adopted by external influence would be to see countries where the laws prohibit this but where such laws are ignored, either
de facto or by explicit policy (a country like Pakistan might be a good example but I can't be sure as I am not competent in history). I am not sure that I am making a terribly meaningful observation with this, though, so I will not make any strong claims of having found a "signature".
