Killer chilli

I got this chilli from Alister at work via a party held by Victor, our Mexican apprentice at work. Victor's mother grew it and it's known as the demon chilli in Mexico. The plant was apparently smuggled over the
border, but I know nothing about that.
I nibbled the end of the chilli and I couldn't feel my lips and half my tongue for half an hour, despite drinking a glass of milk. I cooked the rest into a curry which was considerably hotter than normal. Phew !!
