Polygamy:
the practise of having more than one wife or husband at one time
Polygyny - when a man has multiple wives
Polyandry - when a women has multiple husbands
Polygyny is legal in 58 countries where as Polyandry is confined to a few societies, in many cases in countries with a large Muslim population the law permits polygamous marriage but for Muslims only
Polygamy is against the law in most countries, in the UK anyone who goes through the marriage ceremony whilst still married is bigamy which is punishable by up to 7 years imprisonment, a fine or both
The laws on Polygamy vary from culture to culture mainly depending on religion, the Qur'an permits Muslim men to take up t 4 wives
Polygamy may also be tradition for many places which is why it is considered legal
many Muslim societies criminalise adultery, however several Christian societies in Africa also make it a criminal offence - Punishment varies from death to fines
However in many countries including the UK adultery is legal however is seen as deviant

Laws against adultery are often found in societies where women occupy a very subordinate position
homosexuality is treated as a crime in a number of countries
Male homosexuality is illegal in 72 countries and in 45 so are lesbian relationships
in 6 countries homosexuality can result in the death penalty
In Russia homosexuality is not illegal however the promotion is
Many countries which do not criminalise homosexuality still do not allow same-sex couples to marry or adopt
Many religions had traditionally condemned homosexuality - so countries with a strong religious influence have laws against homosexuality
Polls by Pew Research Centre show higher levels of support for bans on homosexuality in some countries
the fact that male homosexuality is a crime in more countries than lesbianism is, may be due to sexist assumptions by male lawmakers that women were incapable of same-sex attraction
Laws on cannabis vary between different societies - in general the possession of cannabis for personal use is treated more leniently then growing, importing or supplying
In the UK possession of cannabis can be punished by up to 5 years imprisonment and supply with up to 14 years
Some places have legalised cannabis for personal or medical use, others have legalised the sale of cannabis
a lot of places, like Portugal, have lower the sentence for cannabis use down to a misdemeanour or a minor offence
Differences in laws on cannabis to some extent reflect difference in norms and values in different societies
Lawmakers in some society's take the view that the best way to prevent drugs causing harm is by taking a tough stance to deter their use
Lawmakers in other societies see legalisation or decriminalisation as a way to take cannabis out of the hands of criminal suppliers and to reduce the harm by enabling users to get help for their problems
