how does one say marijuana in spanish?

marijuana.
But not like how we pronounce it. We pronounce it as mary(juana) Mary like 'merry'
They pronounce it as mari(juana). Mari like 'mah-ree'

Basically its just the 'mari' part of the word that they pronounce differently.
No idea of the slangs for it though.

There was a website that explained the laws for weed for like every country. It was very helpful and great but I completely forgot what it was.. I sure miss that site.
