What’s the difference between nicotine and thc?
The latter is politically correct.
There isn’t a known toxic amount of THC while nicotine is a neurotoxin (besides being a mild stimulant)?
There's a huge difference in that one teaspoon of nicotine is enough to kill an adult whereas a person would need to ingest 40,000 times the standard THC dose to cause death. (That's the equivalent of smoking 1500 pounds of weed in 15 minutes.)
