How many teaspoons is 20-25 grams of SN?

[JayBot2005]

I don't own a scale and I am too depressed to get one.

Anyone know how many teaspoons is equivalent to a lethal dose of SN?

Also, I've got Olanzapine, is SN and Olanzapine enough?

Again I'm too depressed procure anything else

Thx lovely peeps
Sorry tablespoon is probably closer
