Don't be stupid.
Have you ever heard of "choking highs"?
It's where people who cannot afford drugs, but are hopelessly addicted nontheless, choke each other almost to the point of unconsciousness in order to get that same "high".
Oxygen deprivation to the brain causes it to release painkilling chemicals.
Doesn't mean it's good for you. Sugar and candy are hardly in the same category as pot and heroin.
