I've done Aid work in Haiti, as a nurse. I'm not trying to be judgmental or harsh but..... its one of the worst places I've ever worked & I've worked in war zones. Haitian Voodoo isn't for the weak of heart. I treated burn wounds on people from infants to adults from ritual practice. People doing "spells", or trying to control spirits, hoping it would help the person only resulting in severely harming another person. Some practice is geared toward desiring to get possessed, so sometimes it was self-inflicted. Everything from ingesting harmful substances, cutting, to burning the person. Also its often used as bribery for business, levering it to con business into giving money to break spells or so the shop owner won't be cursed or ward off demons. Mafia style voodoo.
