The Mindbender joint (Kratom) is the most powerfull one.
It gives a strong relaxing effect; Not like Marihuana but rather more like opium.
The Wild Lettuce joint also has a strong relaxing effect.
The Damiana joint is not so strong; But many people, especially women enjoy it.
The Dreamer joint, though not as strong as the Mindbender joint, is effective and very nice.
