These are the most libral countries for pot use:
Australia
Cannabis laws state by state. Decriminalized in Western Australia & South Australia. Tasmania, Victoria, & Queensland policies involve ticketing for below 50 grams.
Belgium
No amount of cannabis is legal to possess in Belgium, however possession of up to 3g of cannabis by adults, for personal use, is tolerated in Belgium. It is also said that 1 female plant is tolerated. Police will take the name of an individual in possession, but the Belgian state will not prosecute. We've been told that a new law to allow for medical use of cannabis has lead the police to be more forgiving about possession of small amounts of non-medicinal cannabis. FA tells us that there is no legal way to buy or import cannabis or its seeds. See ejustice.just.fgov.be (French only). (Thanks CG, FA. Aug 2006)
Canada
Cannabis is schedule II in Canada (for more than 3 kg). Canada's cannabis control laws are spottily enforced, with the west coast (British Columbia) being well known for its high quality cannabis and low levels of enforcement. In 2002, Canada's federal government made several findings in favor of cannabis legalization and medical use approval. Although the status of medical cannabis is still in flux (sep 2002), the Canadian government has several times voiced its intention to support full medical use. Non-viable Cannabis seeds and Cannabis stalks (that do not include leaves, flowers, seeds or branches) are exempted.
Busts in Canada continue, especially of larger growing and distribution operations.
In July 2000, an Ontario Court of Appeal ruled against the Canadian law because it did not address medical necessity and on July 31, 2001 a new regulation was enacted by the cabinet which addressed medical use. In January 2003, a lower Ontario court ruled simple possession laws banning cannabis unconstitutional, although it is unclear what the long term implications of this might be.

Mexico
A new bill, passed by the Mexican Federal Legislature in late April 2006, has not yet been signed into law, but would decriminalize very small amounts of cannabis (under 5g) but would stiffen penalties for larger amounts and remove current discretion judges about the definition of "personal use amounts". See Senado.gob.mx (Spanish Language). Also see SignonSanDiego : Mexico Decriminalizes Drugs. from Cannabis is illegal in all forms in Mexico and possession can result in stiff fines and long jail sentences. Police can often be bribed on the spot and it is said that police plant cannabis on innocent bystanders near the U.S. border in order to solicit bribes from tourists. (Unconfirmed, thanks MW and JH)

Pakistan / Peshawar
We received the following from a contributor:
"In Peshawar and the northern parts of Pakistan, smoking Hash (called Charas here) is socially acceptable and even sold on an open market where the government has no power to intrude. You can be jailed for up to six months if you're caught with Charas in other parts of the country, but it's very very common to bribe the cops with as little as $5-20. Also, many shops have Charas behind the counter, but will not admit to it or sell it unless they know you. Most people who get caught here usually only do so because somebody tipped the cops. Otherwise getting caught for Charas possession is rare." [IM, May 2006]
(Unconfirmed, thanks IM) See Drug Law : Pakistan.
Poland
Possession of cannabis is illegal in Poland. Even small amounts (1g) are not tolerated and penalties can be high. Since Jun 2005 according to the new law, a new resocialization program for drug addicts has been formed as a alternative to putting young people in prison. Cannabis is still a public enemy treated the same way as 'hard drugs'. (Thanks RaN)
Portugal
Cannabis is banned in Portugal in all its forms, however since 2000 consuming and buying small quantities of cannabis (as with all other illegal drugs) is not a crime, it is only punishable by a small fine. Further, in major cities, the police have a rather tolerant atittude towards cannabis consumption and it is largely ignored. Note that anyone found possessing quantities of cannabis more than considered typical for an average user in 10-days can be presumed to be a distributor and can be prosecuted and jailed. (Thanks J)
Romania

For bigger quantities possession or for growing (only for personal use) you can stay 3 or 6 years in prison. If you sell cannabis you can take over 6 years in prison."
