Out in the Amazon they use kerosine as part of the extraction process and dump the gas in rivers afterwards (a water supply is a necessity). Screws with the env. In a lab it's a much more refined process that creates a high-end product. Coca leaves are not illegal in South America but the refined product is.

Relatively new oldfag here. I've been lurking since Jan with the odd post.
Regarding Iran. I remember seeing a news article when the Shah was deposed (late 70s) that claimed his new successor Ayatollah Khomeini had nine fingers when he went into exile in Paris, but ten when he returned to Iran. His followers claimed that it was an act of God, Allah be praised.
This has bugged me for years and I wondered whether it might be a Mandala effect because no-one else remembered it. I was digging the other day and I found this link, which not only suggests that Khomeini was an imposter based on the additional finger, but also gives some excellent background on the revolution that wasn't.
