No no, you're right.

If we're talking about that 90s grunge band, I'm sticking by my antipathy.

But if we mean that beautiful plant Mitragyna speciosa - well, I'm quite fond of that bush.
And here we are both in agreement:
Mitragyna speciosa, common name: Kratom, a tree, growing up to 50 feet tall, native to Thailand and Malaysia. The leaves of the tree are traditionally chewed for their effects, which are described as a combination of narcotic and stimulant. Kratom is used by some as an opium substitute (in tea, smoked, or chewed) and has been found to suppress symptoms of opiate withdrawal. As with opium, it is known for causing constipation, and is sometimes used as a treatment for diarrhea.
